From 735 Official Mock score to 655 on the Real Test

Question

Hi, after scoring 705, 715, and 735 in my last official mocks, I got a 655 on exam day. Quant is my weakest section so I really drilled in the month after my first attempt. My first attempt score was 645 (where the exam literally stopped during Quant and they had to restart the computer so I lost 1-2mins - they even refunded the exam fee). In my 2nd attempt my DI score dipped a bit from 85 to 81, and Quant improved from 73 to 78 (Verbal stayed the same at 88). I am at a loss of what to do because I've exhausted all official mocks and in the actual test Quant was much harder. I know DI can be a bit hit or miss, but Quant being so hard has thrown me off. At the time of my first attempt my highest official mock score was 675, so I def improved significantly in the month I had to prep between attempts.

If the official exam is so much harder than official mocks how could I have even effectively prepared? Feeling very dejected and not sure how to proceed from here. Have others experienced the same thing? Any advice? I have a degree in Econ and work in corp finance so I haven't faced the same level of math as engineers, but don't understand how this score is so bad and how I am just at 50th percentile after 4 months of prep, what am I doing wrong compared to others? How do I proceed?

(I've even done GMATClub and ExpertsGlobal   tests but found the Quant harder than the official mocks so thought they are maybe not representative, and I found Admit Masters too easy)

Hi. Sorry about the score - I have recently talked to someone who kept scoring 755+ on their GMAT Prep and GMAT Club Tests and getting 665 on their GMAT Test - 3 times in a row!!! They finally took the test again and got a 755 for the fourth time! (they were going to give up at 665 if the 4th attempt was that exact number)

It seems that the elusive super high scores on the official mocks are really sensitive to stress and if you are approaching them more relaxed and calmer on a regular day but then stress on the GMAT, the score takes a hit.

P.S. What I have heard from many people is that the official test will be harder than GMAT Prep or OG from Quant standpoint but not quite as challenging as GMAT Club's tests.

I am so sorry you’re going through this. Scoring a 735 on an official mock only to see a 655 on the screen is a massive shock to the system, especially when you’ve put in the work and have a professional background in finance.

First, let’s breathe: A 655 is not a "bad" score. On the GMAT Focus Edition, a 655 is roughly the 90th percentile. The reason it feels bad is the "gap" between your potential and your result. That gap is almost certainly not about your intelligence or your Econ degree—it’s about the specific way the GMAT tests Quant under pressure.

Here is a breakdown of why this happens and how you can bridge that gap.

1. The "Harder Quant" Perception
You are not imagining things, but it’s likely not that the math is "harder" in terms of concepts. Instead, the actual exam often uses wordier prompts or more complex logic traps than the older mocks.

When you are stressed (especially after your first attempt had technical issues), your "executive function" takes a hit. On a mock at home, you might see through a trap in 10 seconds. In the center, that same trap can eat up 3 minutes of panic, leading to a death spiral in your pacing. Since you are in Corporate Finance, you likely have the "math" skills, but you might be relying too much on calculation rather than GMAT logic.

2. The Mock Exhaustion Trap
By the time you get to Mock 5 or 6, or if you retake Mocks 1 and 2, you may be experiencing "inflated" scores. Even if you don't remember the exact answer, your brain recognizes the pathway to the solution faster than it would on a fresh problem. This creates a false sense of security regarding your pacing.

3. The "Percentile" Mindset Shift
You mentioned feeling down about being in the 50th percentile for Quant. It is crucial to remember that the GMAT Focus Quant section is extremely top-heavy. Because the Focus Edition removed Geometry, the remaining pool (Arithmetic and Algebra) is much more competitive. Many people with high total scores have "lower" Quant percentiles because the scoring curve is very unforgiving at the top.

How to Proceed: A Tactical Plan
Acknowledge the "Hidden" Quant Gaps Since you've exhausted official mocks, you need fresh, high-quality "hard" problems. Look for "GMAT Club 700+ level" questions specifically for Data Sufficiency and Algebra. Do not just solve them; explain them out loud. If you can't explain the "shortcut" or the logic to a 10-year-old, you don't own the concept yet.

Master the "Art of Letting Go" In your next attempt, you must give yourself permission to "guess and move on" on at least two Quant questions. Often, students with finance backgrounds feel they should be able to solve every math problem. This pride is a trap. If you spend 4 minutes on one hard question, you sacrifice three easy ones later.

Re-engage with DI (Data Insights) Your DI dip from 85 to 81 suggests that Quant fatigue might be bleeding into your DI performance. Since DI is now a third of your score, you can’t treat it as an afterthought. Focus on "Multi-Source Reasoning" and "Graph Interpretation" where you can use your professional data-fluency to pick up points without heavy "math."

Simulate "Testing Friction" Since the computer restart traumatized your first attempt, your brain is now hyper-vigilant for things going wrong. To combat this, do your next few practice sets in a less-than-ideal environment (e.g., a noisy library or a different room) to build up mental stamina and "disruption immunity."

You are not alone
Many test-takers experience a "score drop" on the Focus Edition because the shorter format makes every single mistake count more heavily against your score. You have the Verbal skills (an 88 is incredible!) and the professional background to crush this. You are currently a high-performer who had a bad day at the office.

Your 700+ mock scores indicate that you already have a solid command of most of the GMAT content. So, from here, it's 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.

A 735 mock proves you have the 99th percentile skills. A 655 exam proves your testing process collapsed under pressure. 
 
The official mocks are static; the real exam is hyper-adaptive. If you spent too long on 2-3 'hard' Quant questions early on, you likely triggered a 'rushed state' where you made silly mistakes on the mid-level questions.  
 
The GMAT algorithm punishes those mistakes far more than it rewards getting a hard question right. 
 
To break 700:

Stop 'Drilling' Math:  You have an Econ degree and work in Finance. You know the math. Your problem is Time Management. You are likely treating the Quant section like a work project where you must be 'perfect.' On the GMAT, perfection is the enemy of a high score.  
   The 'Cut Your Losses' Rule:  If you don't see the path to a Quant solution in 45 seconds, guess and move on. Your goal is to keep your heart rate low so you can preserve your 88 Verbal energy.  
   Exhausted Mocks:  Since you’ve finished the official ones, do GMAT Club Tests, but only in 'Extreme' mode. They are harder than the real thing, which will desensitize you to the 'shock' you felt on exam day.   
 You don't have a 'Math' problem; you have a 'Pacing' problem.

Thank you for the advice! I literally don't think I changed anything, 2 weeks later I did my 3rd attempts, my score has gone from 655 to 725! Make no sense, the quant section was easier for sure, and I think by luck I was tested less in the quant topics I struggle in (quant went up by 6 points). DI also went up by 6 points, back to being close to my first attempt, the variability in this one is also very unpredictable. Quant should be more predictable but it genuinely was a lot easier this time. Nothing is making sense with this exam, 655 to 725 is not an acceptable amount of variability for the same candidate 2 weeks apart.
