This is a common spot, and eight months spent on your reasoning rather than just grinding questions tells me you've taken it seriously. Here's the thing: isolated practice and a full-length mock don't measure the same skill. In a set you know it's CR, you feel the difficulty, you're fresh, you go at your own pace. The mock strips that away — mixed adaptive questions, a clock across the whole section, fatigue and nerves over two-plus hours. Strong isolated accuracy next to a flat score isn't a contradiction, and that gap is what to diagnose.
You asked if it's timing, decision-making, endurance, or focus. It's rarely just one. Maybe the content isn't automatic yet and breaks under adaptive pressure. Maybe it's nerves, which wreck recognition and calculation even on material you know cold. Maybe it's stamina or pacing. Could be a few at once, and each needs a different fix.
The way to find out is to review your last mock or two. Go through every miss, plus the ones you got right but weren't sure about, and label what happened: didn't know it, misread, careless slip, trap, ran out of time, or blanked. Be honest, since "careless" and "trap" often hide a shaky skill. The pattern is your answer. Misses late or left blank point to pacing or stamina; blanking on things you know points to nerves; concepts you never really had, or accuracy sliding as questions get harder, point to depth. Remember the score reflects not just how many you get right but the difficulty of what you get right and wrong, so 80% at a fixed band won't move you up on its own.
One more thing: five mocks over four months barely moving (after building your approach from three different instructors) suggests the pieces don't quite fit together. If your review shows scattered gaps across sections, a single structured course that sequences topics and tracks accuracy will do more than more patchwork.
So: measure with official mba.com tests, review by cause, fix the one that dominates, and consolidate if the gaps are spread out.

Why Is My GMAT Score Not Improving?I hope that helps, and I wish you all the best with your prep.

Hi everyone,
I'm looking for some advice because I'm struggling to understand why my practice performance isn't translating into mock scores.
I started preparing for the GMAT over a year ago.
About 8 months ago, I took the official GMAT twice and scored 515 both times. Looking back, I realized I had rushed into taking the exam before I was truly ready.
Those attempts gave me enough time to reflect on my weaknesses. Over the past 8 months, I've worked systematically on fixing them by following instructors like
GMAT Ninja, Marty Murray, and Aditya Kumar on YouTube. Rather than just doing more questions, I've focused on improving my reasoning process and deploying better strategies for each question type.
The encouraging part is that those changes seem to be working
in isolated practice.
- In Critical Reasoning, I consistently get around 8 out of 10 questions correct in the 605–655 difficulty range.
- I see similar levels of accuracy in Quant, Reading Comprehension, and Data Insights. Across all three sections, I feel much more confident in my approach and accuracy than I did 8 months ago.
- I genuinely believe I've become a better test-taker at the question level.
The problem is that this improvement isn't showing up in full-length tests.
I've taken
5 mocks over the last 4 months, and my overall score has remained stuck around
545. The only noticeable improvement has been a slight increase in my Quant performance during mocks, but overall I'm unable to translate my question-level gains into a higher total score.
I'm trying to understand
what I'm missing.
Has anyone experienced something similar, where:
- You became significantly better at solving questions in isolation across all three sections,
- Your strategies improved and your practice accuracy was consistently good,
- Yet your mock scores barely moved?
If so:
- What turned out to be the root cause?
- Was it timing, decision-making, endurance, maintaining focus over the entire exam, or something else?
- What helped you bridge the gap between practice performance and actual mock/test performance?
I'd really appreciate hearing from anyone who has faced this problem or from instructors who have seen students go through something similar.
Thanks in advance!
