Dustin GMAT’s AI System: A Complete Guide

This document will detail the purpose, usage, and considerations for each tool, helping you maximize platform resources, aid your review, and effectively improve your abilities.

Leveraging AI to Solve the Dilemma of Traditional Question Review

This guide aims to introduce a new method for GMAT test-takers to conduct efficient and in-depth question review with AI assistance. The core objective of this method is to resolve the pain points of traditional review methods, where “saving time” and “ensuring effectiveness” are difficult to balance, allowing test-takers to truly learn from their mistakes.

The Predicament of Traditional Review

• Fast but not in-depth: Only looking at text explanations or solution videos allows test-takers to understand how to solve “this question,” but fails to identify “their own” blind spots in thinking, leading to repeated mistakes on similar questions.
• In-depth but extremely time-consuming: Recording one’s problem-solving process and comparing it with standard solutions can precisely pinpoint issues, but the process is very slow and a heavy burden for test-takers with limited time.

Solution: Personalized General AI Problem-Solving and Analysis Model

Dustin has developed an AI model that integrates and structures the knowledge system from all his courses. It is not just a problem-solving tool, but a personalized learning diagnostician.

• Applicable to all question types: This AI model is not limited to specific subjects and is applicable to all types of test questions.
• Adopts course methods: It can analyze questions entirely according to the standard problem-solving processes and thinking patterns taught in class (e.g., identifying question types, role-playing, anticipating positions, etc.).
• Personalized error analysis: It not only provides the correct answer but also compares the user’s problem-solving approach with the standard process, precisely pointing out where the user deviated (e.g., question type identification, method selection, option analysis).

Recommended AI Review Three-Step Process

Dustin suggests categorizing questions into three types and adopting different review strategies:

1. Questions answered correctly with no doubts

Handling method: Can be skipped directly, no review needed.

2. Questions answered incorrectly or with uncertainty, but where the sticking point is clear

Example: Hesitating between two options, or unable to deduce a certain logical step.

Processing steps:

1. Directly provide the question to the AI, ask about the uncertain steps or options, and engage in interactive learning with the AI.
2. After reviewing, organize the “diagnostic tags” or problem summaries provided by the AI into your “error log.”

3. Questions answered incorrectly with no idea what the problem is

This is the most critical type of review. The processing steps are as follows:

1. Do not look at the detailed explanation yet.
2. Record or write down your complete thought process that led to the incorrect answer in detail.
3. Paste this “incorrect thought process” text to the AI and ask: “This is my solution, please tell me what the problem is.”
4. The AI will compare your process step-by-step, pointing out the differences between your approach and the correct process in areas like “question type identification,” “problem-solving method,” and “option analysis,” and then summarize the issues.
5. Finally, upload the “diagnostic tag” directory and organize these issues into your “error log” by category.

Best Practices for Interacting with AI & FAQ

Before you start, please read the following tips, which will help you interact more smoothly with the AI tools on the platform.

Q1: What if the AI doesn’t fully follow instructions, or starts doing things it shouldn’t (e.g., the “Classification Tool” starts solving problems)?

A: This is the most common scenario. Simply tell it: follow your instruction. This command will remind it to return to its original task. If the problem persists, the simplest and most effective solution is to delete the current conversation and open a new window. This resolves 99% of issues.

Q2: Why do I need to keep starting new conversations?

A: The AI model remembers the context of the current conversation. When a conversation becomes too long, old information may interfere with the execution of new tasks, leading to decreased performance or errors. Therefore, after completing an independent task (e.g., reviewing a question, generating an article), it is strongly recommended to open a new, clean conversation window to ensure optimal results.

Q3: What if the AI’s answer is too long/too short/too complex?

A: You can always issue follow-up commands to fine-tune the output. For example:

• Please explain in detail
• Summarize it into three points for me
• Explain with a simpler analogy
• cut in smaller chunks (when Enhance Reading Speed segments are too large)

Q4: Where can I find these tools?

A: This document aims to explain the functions of all tools. You can find the corresponding tools in the toolbar on the left side of the Dustin GMAT AI Platform.

Usage Recommendations and Important Reminders

To maintain the quality of AI output and maximize its effectiveness, please note the following:

Principles for Handling Chart/Graph Questions

• Prioritize text: If the charts or graphs in the question can be copied and pasted as text, do so directly. It doesn’t matter if the formatting is messy; the AI will automatically clean and understand it.
• Secondly, use images: If it cannot be converted to text, then use screenshots.
• Beware of image recognition errors: The AI may make mistakes when recognizing numbers or text in images, but its analytical “problem-solving logic” is usually correct. When reviewing, pay attention to this point and focus on its logical analysis rather than just the text recognition results.

Using the Chat Window

• On a “daily” basis: It is recommended to use one chat window per day. After reviewing for the day, open a new window the next day. This prevents a single conversation history from becoming too long, which could cause the AI to forget previous conversation details and affect analysis quality.
• Uploading diagnostic tag files: In the same chat window (discussion box), diagnostic tag-related files only need to be uploaded once. Repeated uploads will lead to excessive data, which will also affect the AI’s analysis performance and accuracy.

Other Reminders

• If you still don’t understand the AI’s explanation, please refer to relevant solution videos or ask the instructor directly.
• If the AI produces unexpected errors or answers, please take a screenshot and report it to Dustin to help optimize the model.
• If you find this tool useful, don’t forget to share your positive feedback with Dustin!

Detailed Explanation of AI Tools

(I) Starting Point: Your AI Prep Advisor

1. The Router to Tools

• Problem solved: When reviewing incorrect questions, you are unsure of the root cause of your mistakes and don’t know which platform tool to use for the most effective review.
• How it helps: This is the central hub of the platform. It acts like a “pharmacist”; you describe your “symptoms” (i.e., the mistakes you made while solving problems), and it helps “diagnose” the underlying weakness tags and prescribes the most suitable “medicine” (i.e., recommends which tools to use and in what order).
• Interaction method:
  1. After comparing with the detailed explanation, describe your problem in natural language, for example: “I misunderstood the conclusion,” “I chose B when it was a 50/50, but the answer is A,” or “I couldn’t come up with a pre-thinking direction.”
  2. You can also directly refer to the “Diagnostic Tag Directory” provided by the instructor and tell it your problem tags to get the most precise recommendations.
• Notes: This is the most efficient starting point for using this platform. Instead of guessing which tool to use, let the “pharmacist” guide you first.

(II) Classification and Diagnostic Tools

2. Classify this question (CR / TPA)

• Problem solved: Inability to accurately determine the official sub-category of CR (Critical Reasoning) or TPA (Two-Part Analysis) questions.
• How it helps: This tool automatically classifies the questions you input into four main categories according to official standards: `Analysis`, `Construction`, `Predict`, and `Plan`. This helps you quickly tally incorrect questions and identify weak question types, allowing you to adjust your study plan.
• Interaction method: Paste the questions from your error log that you answered incorrectly or struggled with (you can include multiple questions at once, either the full text or just the stimulus and question stem).
• Notes: Its sole function is “classification,” not “problem-solving.”

3. Classify this question (RC / MSR)

• Problem solved: Inability to accurately determine the question type for RC (Reading Comprehension) or MSR (Multi-Source Reasoning).
• How it helps: Classifies questions into five main categories: `Main Idea`, `Pure Text Detail`, `Inference`, `Function`, and `Logic` questions, helping you pinpoint weaknesses in reading comprehension question types.
• Interaction method: Batch paste RC / MSR questions from your error log that you answered incorrectly or slowly.
• Notes: Used only for classification, not for problem-solving.

4. Classify this question (PS / DS / TPA math)

• Problem solved: Need to quickly organize math error questions to identify weaknesses in core math concepts.
• How it helps: This tool analyzes multiple incorrect questions you provide based on the 12 official GMAT math concept categories and generates a frequency statistics table, clearly showing your weakness distribution.
• Interaction method: Batch paste math error questions or timed-out questions from your error log on weekends or before a consultation.
• Notes: Its purpose is “classification statistics,” not “problem-solving.” The quantity of questions provided at once should not be excessive.

(III) Reading and Text Comprehension Tools

5. Rewrite Passage into GMAT Style

• Problem solved: Lack of GMAT-style academic articles for extensive reading practice. You might only have general news, Chinese materials, or “Jijing” (exam memory dumps) which are non-standardized materials.
• How it helps: Rewrites any article you provide (Chinese or English) into a GMAT-like reading passage with GMAT academic tone, style, and structure, infinitely expanding your reading training materials.
• Interaction method: Simply paste the text you want to convert (e.g., Chinese Jijing, news reports, English articles on specific topics).
• Notes: Its function is “rewriting,” not “summarizing.” To maintain rewriting quality, it’s recommended to convert one article at a time.

6. Train your close reading skill (Train Predictive & Active Reading)

• Problem solved: When reading short passages in CR or RC, information often fails to combine or is misunderstood. The root cause is often “reading without understanding,” failing to convert text into verbal information that can be thought about.
• How it helps: The tool displays one sentence at a time and asks you to explain it in your own words. It evaluates whether your understanding has logical deviations, thereby training your “pre-processing” ability for information.
• Interaction method: Input a short text (CR or TPA stimulus is recommended, text should not be too long). For each sentence presented by the tool, look away from the original text and use your memory and spoken language to state the meaning of that sentence, then type your reply.
• Notes: Absolutely do not translate word-for-word. The goal is to confirm whether you can restate it in your own thinking language, not to test translation skills. This training does not require timing; accuracy is prioritized.

7. Enhance Reading Speed

• Problem solved: Slow reading speed due to habit of reading word-by-word instead of by semantic chunks.
• How it helps: This tool automatically segments the article into semantic chunks. This trains your eyes to habitually jump between chunks, thereby improving reading speed.
• Interaction method: Paste the article you want to use for reading training. If you feel the segments are too large, you can tell it cut in smaller chunks.
• Notes: This is a training tool specifically designed to “improve reading speed”; please use it in your daily reading practice.

8. Rewrite Passage into Complex Sentences

• Problem solved: Reading ability is hindered by long and grammatically complex sentences, even if vocabulary and domain knowledge are not an issue.
• How it helps: Rewrites the text of any question you provide (regardless of subject) into a “boss-level” version with longer, more complex sentences, without changing the original logic and meaning.
• Interaction method: Simply input the questions you usually practice.
• Notes: This is a form of “grinding”; once you get used to these high-difficulty sentences, normal GMAT questions will feel exceptionally easy.

9. Sentence Cracker

• Problem solved: When encountering a specific difficult sentence, you are unsure if the problem lies in “vocabulary” or “sentence structure,” and you need a targeted solution.
• How it helps: This is a three-step deep analysis tool: simplify, diagnose, practice. If the problem is in sentence structure, it will break down the grammar and then generate five new sentences that are different in story but identical in syntactic structure for you to practice repeatedly.
• Interaction method: Input a single sentence that you don’t understand or misinterpret. Then interact with the tool according to the prompts.
• Notes: It can help you thoroughly conquer any long, difficult sentence you fear through “customized sentence generation.”

10. Explain Textbook

• Problem solved: Difficulty understanding abstract concepts, formulas, or logical principles in handouts, OG, or textbooks.
• How it helps: After receiving an abstract concept, it explains it using concrete, real-life examples or analogies and designs small quizzes to test your understanding.
• Interaction method: Simply input the text or screenshot of the abstract concept.
• Notes: This tool is not for solving GMAT questions but for assisting in understanding core concepts in learning materials.

11. Understanding Logical Terms

• Problem solved: In high-score CR, RC function questions, or TPA questions, you don’t understand the specialized, abstract logical terms used in the options.
• How it helps: Specifically explains the precise meaning of these abstract logical terms in specific question options and the logical relationships they represent.
• Interaction method: Input the complete question with options containing abstract logical terms.
• Notes: The feature of this tool is to explain “abstract logical terms,” not general problem-solving.

12. Passages You Failed to Organize

• Problem solved: Lack of structural understanding when reading articles; although individual paragraphs are understood, the logical relationships between paragraphs are not.
• How it helps: Automatically generates a keyword outline of an article, allowing you to compare it with your own outline to review your understanding of the article’s structure.
• Interaction method: You must first organize the article’s structure yourself, then input the article and use the tool-generated outline for comparison and verification.
• Notes: Applicable to all long articles with logical connections, such as CR, RC, TPA, MSR.

(IV) Specific Question Type Enhancement Tools

13. Customize Your Preferred Problem-Solving Process

• Problem solved: Difficulty integrating multi-page information in MSR questions, and not accustomed to standard problem-solving processes, hoping to find a method that suits you.
• How it helps: This tool can demonstrate problem-solving according to your specified problem-solving process.
• Interaction method: Provide the various parts of the MSR question and describe your preferred problem-solving order in text.
• Notes: The focus is on “demonstrating the thinking information flow,” not just providing answers.

14. Boldface Interactive Tutor

• Problem solved: Poor grasp of CR Boldface questions, inaccurate judgment of the function of sentences in the passage.
• How it helps: Guides you sentence by sentence to analyze the entire passage, determine the function of each sentence, and provide instant feedback.
• Interaction method: Paste the complete BF question and mark the boldface parts with square brackets [ ].
• Notes: The training focus is on the function of “every sentence” in the passage.

15. CR-BF: Demo Thoughts

• Problem solved: Already mastered BF question identification, but want to learn faster, more practical problem-solving strategies.
• How it helps: Directly demonstrates the special problem-solving process designed by the instructor, such as first looking at option differences and then locating them in the text.
• Interaction method: Paste the complete BF question and mark the boldface parts with square brackets [ ].
• Notes: Focuses on “demonstrating the problem-solving process.” It is recommended to review with the `Interactive Tutor` first, then use this tool to learn faster solutions.

16. Logical Chain Builder

• Problem solved: When doing CR `Argument Evaluation` type questions, you misidentify the logical chain or cannot clarify the thinking gap.
• How it helps: You first determine the “starting point” and “ending point,” and the tool will show you a detailed logical reasoning chain for you to compare and check.
• Interaction method: Input the argument text and tell it your determined “starting point” and “ending point.”
• Notes: Aims to “construct and clarify the logical chain,” not to directly select the answer.

17. Role-immersion Trainer

• Problem solved: Difficulty with the “role-playing, perspective-taking” method when doing CR `Argument Construction` questions.
• How it helps: Suggests a suitable “stakeholder role” to adopt and guides you to make “pre-thinking” from that role’s perspective.
• Interaction method: Input the stimulus and clearly tell the tool the official sub-category of the question.
• Notes: This is a review tool used to train thinking methods for specific question types.

18. Identify Core Issue

• Problem solved: Unable to grasp the core proposition or conclusion of the passage, leading to an inability to judge the relevance of options.
• How it helps: First helps you organize the “central proposition” of the original text, then generates two “analogy stories” to test your ability to grasp the proposition of new stories.
• Interaction method: Input the argument text of the passage.
• Notes: Specifically trains “identifying the core proposition” and “judging relevance.”

19. Review Distractor (Trap Choices)

• Problem solved: In Verbal questions, you always choose the wrong option in the final 50/50 choice.
• How it helps: Completes knowledge transfer through three steps: “analyze the trap -> real-life analogy -> analogy variation test.”
• Interaction method: Paste the complete question, including the two options you hesitated between, clearly marking which is the correct answer and which is the trap option.
• Notes: Only applicable when you have narrowed down the options to the final two.

(V) Content Generation and Practice Tools

20. Create Variant Question

• Problem solved: Official practice questions are limited, and you want more practice for specific weaknesses.
• How it helps: Rewrites a GMAT question you provide into a “variant question” that has a completely different surface story but identical underlying logic, concepts, and option design.
• Interaction method: Simply input a complete question.
• Notes: The function of this tool is to “create new questions” for practice, not to “solve problems.”

21. Train Reading for Specific Domain

• Problem solved: Reading difficulties or fear in specific academic domains (e.g., astronomy, biology).
• How it helps: You specify your weak domain, and the tool generates GMAT-style articles in that domain for you to practice, and comments on your summaries.
• Interaction method: Tell the tool your weak domain, then interact according to the prompts.
• Notes: Aims to overcome domain fear through extensive, targeted reading.

22. Memorizing Vocabularies

• Problem solved: Insufficient vocabulary, and traditional memorization methods are ineffective.
• How it helps: Adopts a three-pass learning process of “example sentence learning -> deepening understanding -> article connection” to consolidate memory in context.
• Interaction method: Provide no more than 20 words at a time, then follow the tool’s guidance to complete the three-pass process.
• Notes: Do not exceed 20 words at a time to ensure article generation quality.

23. Finding Similar Questions in Set

• Problem solved: Need to find questions similar in concept to a specific math error question from a large new question bank for practice.
• How it helps: You provide a “target question” and a “question pool,” and the tool automatically compares them to find the most conceptually similar questions.
• Interaction method: Provide 1 “target question” and a “question pool” separately to the tool.
• Notes: It is not responsible for problem-solving; its purpose is “question matching.”

24. Identify Features for Applying a Specific Solution

• Problem solved: You understand the solution to a certain math question, but when encountering a different question later, you still cannot recognize that the same solution should be used.
• How it helps: Analyzes the solution to a question and tells you which specific descriptions or features, if they appear in other questions in the future, should prompt you to recall this solution.
• Interaction method: Simply input the math question for which you cannot recognize the solution.
• Notes: This is training for “knowledge transfer.”

25. Convert to Real-context

• Problem solved: Performs well on pure math calculation questions but gets stuck on word problems.
• How it helps: Automatically adds a story layer to the “pure math question” you provide, turning it into a word problem.
• Interaction method: Simply input a pure math question.
• Notes: Aims to train your ability to handle word problems.

(VI) General Problem-Solving and Review Tools

26. Question you did wrong

• Problem solved: Need a quick, direct explanation of a solution.
• How it helps: Provides a simple and straightforward explanation for questions you answered incorrectly.
• Interaction method: Input the question you answered incorrectly.
• Notes: The problem-solving process provided may not always be the best practical method for humans. To learn “problem-solving processes,” it is recommended to focus on solution videos.

27. You did it right but slowly

• Problem solved: You answered the question correctly, but it took too long, and you hope to find a more efficient solution.
• How it helps: Simulates how a human would think in an exam setting to quickly solve problems using techniques or shortcuts.
• Interaction method: Input the question that took you too long to solve.
• Notes: Can only solve problems for a single question. To improve fundamental abilities, you still need to return to the “core review process.”
