I'm an engineering grad who moved into finance, and this exam took me five attempts across a year and a half: 645, 655, 655, another 655, and finally a 675 with a perfect Q90. The gap between my fourth 655 and the 675 was twenty days, and in those twenty days I changed almost nothing about my concepts — because there was nothing left to change. What I changed was how I treated the exam. Here's the honest breakdown.
Where I startedMy diagnostic came back around 575. I gave free mocks across a few platforms just to understand the syllabus, read debriefs from actual scorers on forums, and picked my course from there. The first three or four months were purely foundation: go through the full module, then use the module questions to find out what's actually broken. The
error log became my single most important habit — every mistake got classified as execution error, process error, conceptual gap, or timing. Once you can name the mistake, you stop "studying harder" and start fixing the specific leak. That distinction carried me the whole way.
Quant — the Q90, and the ego problemComing from engineering, the math itself was never the issue — across my five attempts I scored Q90 three times. The issue was the attempts where I didn't. Every single non-perfect quant score traced back to the same thing: I'd hit a question I couldn't crack, take it as a personal insult, and burn four or five minutes proving a point to nobody. The hardest skill I learned wasn't a formula, it was "review and move on." Flag it, leave it, come back with whatever time is left. It sounds trivial. It is the entire difference between Q87 and Q90.
One more thing that genuinely helped: practicing on questions harder than the real exam. My weighted accuracy on quant was around 85% on my platform's question bank, which runs noticeably tougher than the actual test — so on exam day the real questions felt easy. If you're consistently accurate on hard questions, keep moving up in difficulty. Comfort is not the goal.
Data Insights — my strategy, and the mistake that cost meI break DI into four buckets: data sufficiency, graphs, two-part analysis, and multi-source reasoning — roughly in that order of difficulty for me. My rules:
DS: after you've confirmed statement one is sufficient, give statement two the same attention — that's where the traps live. Never finish a calculation once sufficiency is established. And do these questions fast; they're the cheapest points in the section.
Graphs: read the graph before the question. Know what it's saying first, then the questions become quick.
TPA: quant-based TPAs are usually just an algebraic equation — finish those under 2 minutes, hard stop at 3. Verbal TPAs are time sinks — hard stop at 3 to 3.5 minutes, no exceptions.
MSR: here's my confession. My mock strategy was to park MSR for the end, and on exam day I reached it with 7-8 minutes left — and got the entire set wrong. All three, consecutively. And the algorithm punished it brutally: I've scored 15/20 in DI before and gotten an 83 (about 95th percentile). This time, the same 15/20 gave me an 80 — purely because the errors were consecutive. Spread-out mistakes and clustered mistakes are not the same thing to this exam. Accept before you walk in that you'll see hard questions; that acceptance alone protects you from the panic-spiral that creates consecutive errors.
Verbal — losing the first question, and what it actually costsVerbal was my weakest section and I'd made peace with that. On exam day I couldn't hold my nerves early — out of the first eight to ten questions I got five wrong, including question one. Then I settled and ran roughly twenty questions in a row correct. Final tally: around 18-19 correct out of 23. People have scored V85 with that raw count. I got V81, because my wrong answers were front-loaded and clustered. Same lesson as DI from the other direction: the first few questions are disproportionately expensive, and consecutive errors compound the damage. Slow down at the start. The exam will give you the time back later.
And the bigger lesson: accept your weakness. I knew verbal wasn't going to carry me, my mentor told me to stop obsessing over it, and I countered it with Q and DI instead. Past 645-655, the difference between you and a 725 is not concepts — it's execution. All of it.
Mocks — treat them like the exam or don't botherLast year, almost every mock I took was interrupted. Your brain gets tired, there's a natural pull to pause, come back fresh, and enjoy the inflated score. It's the single worst thing you can do — the real exam has no pause button, and I walked into my real attempts with fake stamina. This year I took mocks at a café, at 10 AM sharp — my actual slot time — arriving 30 minutes early, same clothes I'd wear on test day, same coffee, no interruptions. Then a full day analyzing each one through the
error log.
Of everything I tried, my platform's five mocks were the closest to the real exam — I'd taken fifteen mocks elsewhere the previous year and the verbal was nowhere near real difficulty, which quietly miscalibrates you. In the final month: four full mocks with equal gaps, the last one 3-4 days out. Between them, sectional mocks stacked back-to-back to simulate the real sequence — verbal, then quant, then a 10-minute break, then DI. And the last day before the exam: nothing. Zero study. That's not laziness, that's the plan.
The 20 days that broke the ceilingAfter three 655s there was genuinely nothing left to fix in content. The change was behavioral. Earlier I was sleeping less, waking early, grinding five-six hours a day — and it was actively hurting me. Diminishing returns are real. I cut to a hard max of three hours a day, and some days in that stretch I studied 45 minutes. What I didn't do was miss a single day — consistency compounds, and it compounds negatively the moment you skip.
The other half was psychological, and this is where having a mentor in the last mile mattered more than any question bank. Whenever I felt down I'd get on a call, and I'd come out of it lighter. The message that stuck: stop putting your entire life's stakes on one sitting. Worst case, you rebook in 15 days. I walked in carrying that, and for the first time in five attempts I wasn't fighting my own nerves the whole way through.
If you're starting, or if you're stuckStarting out: be consistent above all — don't miss days. Practice untimed first and fix your strategy per question type (pre-think in CR, graph-first in graphics, statement-two discipline in DS) until it's automatic,
then go timed near the end. Maintain the
error log from day one.
Stuck at a ceiling: your problem is almost certainly not concepts. Find your specific weakness — mine was confidence and nerve management before the exam; yours might be different — and act on that, not on another 500 questions. Study less, sleep more, and stop treating the attempt as final. Be confident. That's genuinely the last mile.
Happy to answer questions. Good luck.
