How to Improve gmat score

Question

Hey I recently took my first gmat exam after a month of prep and got 645 (q84 v82 di79). What can I do to get 685+ in 2-3 weeks

My mock scores were 665 675 695 and 655

Your mock scores indicate that you already have a strong command of much of the GMAT content. So, from here, improving your score is a matter of identifying and strengthening all remaining areas of weakness. So, be sure to thoroughly analyze your practice tests and practice sessions to identify those weaknesses. Then, for each area of weakness: 
- Carefully review all of the properties, formulas, techniques and strategies related to that topic
- Locate and answer dozens of questions that test that topic.

For each question you answer incorrectly, ask yourself: 
- Did I make a careless mistake? 
- Did I incorrectly apply a related formula/property/technique? 
- Did I fall for a trap answer? If so, what was the trap exactly? 
- Was there a concept I did not understand in the question?

By carefully analyzing your mistakes, you will be able to fix your weaknesses efficiently and, in turn, improve your skills. This process has been proven to be effective for all topics.

One approach that would work is doing streaks method practice in any topic that's relatively less strong for you.

For instance, to increase your Data Insights score, you could first shoot for streaks in Data Sufficiency, if you're not already strong there, and then work on the other question types the same way.

This post covers in detail how to use the streaks method.

Also, for some examples of people who used the streaks method to get good results, see the following posts.

A 645 with mock averages in the 660s is actually a strong baseline — you're not far off at all. The thing that stood out to me in your breakdown is the DI79. That's your lowest subscore and the one with the most upside in 2–3 weeks, because Data Insights mistakes tend to cluster around a small number of fixable habits rather than broad knowledge gaps.

Before drilling more questions, I'd spend two sessions doing a proper error analysis on your DI questions from mocks — specifically separating out where time was the issue versus where it was a conceptual gap. For most people at your level, it's pacing in Multi-Source Reasoning and misreading tables in Graphs & Tables, not the underlying math. Once you know which it is, the fix is targeted and fast.

For Quant and Verbal at Q84/V82, you're already in a decent place — focus on eliminating careless errors there rather than learning new content. Two to three weeks is enough time to hit 685+ if the work is specific. You're closer than you think.

Hello  xooging566 ,

Good first attempt after a month of prep; your target score is completely achievable.

Here is a structured, step-by-step approach to help you push through:

1. Consolidate your concepts
Revisit all the conceptual material you have covered so far and work on strengthening it. If you are still struggling with certain topics, consider investing in a solid prep course. Keep in mind: while the official material is excellent for practice, it is not designed for teaching concepts from scratch.

2. Re-attempt all previously incorrect questions
Review your mistakes from earlier practice. Understand why you got them wrong and how to avoid those errors going forward.

3. Practice with a new set of high-difficulty questions
Use either official sources or reliable third-party material to build deeper familiarity with challenging questions.

4. Practice consistently
Every week, go back and re-attempt your earlier incorrect questions. Continue revisiting weak areas in your conceptual understanding along the way.

By diligently following these four steps over a few focused weeks, you will likely find yourself performing at a significantly higher level.

All the best!
