Cannot Breakthrough Quant (Q79-81) After Months of Prep

Question

Hi All! Would really, really appreciate any help regarding the following, I am honestly not entirely sure how to fix but determined to do so:

I studied TTP on and off for some time before honing into studying for the exam holistically around three weeks ago. At that time, I took a mock test to get a baseline and realized my Q score was astonishingly lower than I expected.

For the last 3 weeks I hammered into Q, doing 700+ Qs in the GMAT Club database and repping out mini adaptive quizzes (~10-20 Qs). I diligently took notes on all of my mistakes and common errors, and polished up on all of the concepts minus a few (e.g. Overlapping Sets is one I definitely need to go back to). I could see myself improving through my GMAT Club quiz performance: being given higher-level Qs via their algorithm, recognizing similar Qs and becoming more comfortable, etc. I thought I was almost certain to see improvement in Q and thus my overall score. But I was wrong:

I took one practice test and one official exam (unfortunately, even though I didn't feel completely ready, I could not reschedule and receive a full refund at this time), and scored a Q79 or below in the Q section both times and never received a question that felt quite at the level that I had grown accustomed to being given in GMAT Club. In other words, I think I was only served easier Qs via the algorithm and my score was lower as a result; I was never able to truly show my ability with the higher-level Qs.

I understand there may be a few conceptual gaps I need to fill, plus a greater level of consistency with the easier-level Qs; I plan on addressing these via the GMAT Club database. But I am wondering: (1) Has anyone had a similar issue with the GMAT Q algorithm, where you're stuck receiving easier Qs despite having the capacity to answer harder Qs consistently? Is this a byproduct of not being able to answer the easier Qs consistently enough (say, >90% correct) or the harder ones (say, >50% correct)? (2) How did you address this issue yourself / how would you go about doing so now? Should I transition to practicing more with the Official Guide Qs > GMAT Club forum Qs?

Any help is greatly appreciated. Thank you in advance!

Hi attila14s,

To answer your questions:
1. Yes, your accuracy in easy questions, and to some extent whether you can build a long enough "streak" of correctly answered questions, determine whether the algorithm will throw some medium questions. And then if you can answer correctly a series of medium questions, you'll get to hard questions. That's just the adaptive nature of GMAT algorithm put in a simplistic way.
So it's much more important to build up high accuracy in easy and medium questions than working on the hard ones.

2. At Q79, you likely still have gaps in certain quant topical areas, as you recognize yourself. Imo, the key is to practice and review by topic, as well as to work from low difficulty to high difficulty. If you have not been exposed to OG questions, sure that will be a great source. In GMAT Club PS forum, GMAT Prep (Classic) and GMAT Club Test questions are also good to work on.

Here are two articles that may be useful to you:

If you don't mind posting the Time Management and Performance charts in the score reports from both your mock and real test, people may be able to give you more specific advice.

All the best.

It sounds like you’ve hit the "accuracy trap" that many high-potential GMAT candidates fall into. Because you asked for honesty and a direct assessment of your preparation, I’m going to be candid:  The algorithm isn't broken; your foundation has cracks. 
If you are scoring a  Q79  (which is roughly the 30th-40th percentile on the Focus Edition), the algorithm is doing its job. It isn't "stuck"—it is successfully identifying that you haven't mastered the easy and medium questions yet.
1. The Reality of the GMAT Algorithm
The GMAT is an  item-response theory  (IRT) exam. It doesn’t care how many 700-level questions you can get right if you are missing 500-level questions.
 
  The "Floor" vs. The "Ceiling":  Hard questions set your  ceiling , but easy/medium questions set your  floor . If you miss an easy question, the algorithm "punishes" your score severely because it loses confidence in your ability. It will not serve you a hard question until you prove you can consistently handle the basics. 
  The Accuracy Threshold:  To break into the Q82+ range, your accuracy on Easy questions needs to be near  100% , and Medium questions should be around  80-90% . If you’re missing even 2 or 3 "easy" ones due to "silly mistakes," the algorithm will keep you in the basement.  
2. Why GMAT Club "700-level" Practice Can Be Deceptive
GMAT Club is a fantastic resource, but "hammering" 700+ questions when your baseline is a Q79 is like trying to run a marathon before you can walk a mile.
 
  False Confidence:  High-level questions often rely on "tricks" or niche shortcuts. If you learn the trick for a hard question but lack the mechanical speed for a simple algebra problem, you'll fail the actual exam. 
  The "Niche" Problem:  Official hard questions are hard because of logic; unofficial "hard" questions are often just hard because they are tedious or involve obscure rules.  
 
3. Your Action Plan (The Honest Fix)
If I were coaching you, here is exactly where I’d tell you to work hard:
    Phase  
  Focus Area  
  Goal  
 
   Step 1: The Foundation  
 Go back to TTP or the Official Guide. Focus exclusively on  Easy and Medium  questions. 
 Achieve  100% accuracy  on Easy sets of 20 questions. 
 
   Step 2: Error Log Audit  
 Categorize your mistakes. Are they  Conceptual  (didn't know how),  Strategic  (took too long), or  Silly  (misread the prompt)? 
 If >30% are "Silly," you have a  process  problem, not a math problem. 
 
   Step 3: Timing Pressure  
 Practice in blocks of 10-15 questions with a timer. 
 Learn to "punt" (guess and move on) a hard question to save time for the easy ones you  must  get right.

4. Transitioning to Official Material
 Yes, you should transition to Official Guide (OG) questions immediately.  GMAT Club is great for volume, but the "flavor" of official questions is unique. Use the  Official Prep Question Banks  or the  OG 2024-2025 . Official questions have a specific "logic" to them—they are rarely about heavy calculation and almost always about a property or a relationship.
Summary of Advice
Stop chasing the "700-level" dragon for two weeks. You are likely missing easy questions because you are looking for complexity that isn't there, or you're rushing to get to the "real" questions. On the GMAT,  the easy questions ARE the real questions , because they are the gatekeepers to the high scores.

Hi  attila14s ,

You have made some valid observations. The questions on the official test are not always at the same difficulty level as those on GMAT Club sectionals, and that holds true even for people who score perfectly. The official test is designed for test takers with different skill levels, so the algorithm spreads difficulty across the section. While it does increase difficulty as you build accuracy streaks, it does not push it too high because you still have to solve those questions within strict time limits.

GMAT Club tests, on the other hand, were initially designed to help people score higher. As a result, they include a larger proportion of harder questions, assuming test takers can handle easy and medium questions comfortably.

In your case, I would recommend first aiming for around 90 percent accuracy on easy and medium questions. As you practice, identify and fix any conceptual gaps, as this will have the biggest impact on your overall score. Quant heavily penalizes mistakes on easier questions, so getting even one or two easy questions wrong can drop your score significantly, sometimes to around Q80, even if everything else is correct. If you are targeting a Q85 or higher, avoiding silly mistakes on the easier side is critical.

You should definitely practice all the official questions you can access, but in my experience, they tend to be on the easier side overall. Once you are done with those, it makes sense to supplement your prep with some tougher question sets if you are aiming for a top Quant score.

Hi  attila14s ,

Perhaps, but for the scores you're targeting, it's no longer about just the easy questions. You'll most likely need that kind of accuracy on the entire section. The ESR makes it very hard to see this, because it includes experimental questions, but you may need to target max 2-3 mistakes on the real questions to break out of the Q79-81 range (and even that doesn't guarantee a Q82-83+).

As you suggested, you probably have to just become super consistent in easy and medium questions to get to the higher difficulty questions. If you miss easy or medium questions, the test keeps you at easier levels.

Using the streaks method is a great way to develop the consistency you need.

It’s completely understandable to feel a bit discouraged here. You put in a lot of work and expected to see a clear jump, so seeing similar Quant scores can be disappointing. The good news is that what you’re describing is common, and it usually comes down to how the test adapts, not a lack of ability.

The GMAT rewards strong performance on easy and medium questions before it starts giving you many hard ones. If accuracy or timing slips early, the exam does not move you up to higher-level questions, even if you are capable of solving them. This can create the feeling that you are stuck getting easier questions and cannot show your true level.

At this stage, the focus should shift from doing many questions to doing them carefully. Instead of large batches, work in smaller timed sets and review them deeply. After each set, ask why you missed a question, whether it was a concept gap, a setup issue, or a pacing mistake. That review is what changes your habits. Simply recognizing a question type is not enough. The goal is consistent execution under time pressure.

It also helps to mix sources wisely. Official questions are the closest reflection of real exam style and difficulty, so they should be a regular part of your practice.

Finally, be disciplined about when to move on during the test. Spending too long on one tough question often hurts more than guessing strategically and protecting the rest of the section. When accuracy on easier and medium questions becomes steady, the harder questions will appear naturally, and your score usually improves.
