I did the GMAC Focus Edition, not the classic GMAT, and they're different enough that your prep needs to be specific to which version you're taking. Total prep time was about 10 weeks, starting at 1.5 hours a day and ramping to 3 hours in the final 3 weeks. Starting diagnostic was a 485, finished with a 615, which was enough for the programs I was targeting.
Quantitative reasoning on the Focus Edition is harder to prepare for than people say. It's not traditional algebra — it's data sufficiency and multi-step reasoning, which means the learn-the-formulas approach only gets you so far. I drilled pure quant for the first 5 weeks and hit a plateau around week 6 until I switched to reasoning patterns rather than computation speed.
Verbal is more manageable if you read actively every day during prep. I did about 20–30 minutes of dense reading each morning — financial news, academic abstracts, case studies — and my critical reasoning speed noticeably improved over about 4 weeks. Reading comprehension passages on the actual exam are dense and time is tight.
Data Insights is the section that catches people off guard. It's unique to the Focus Edition and combines data literacy, table analysis, and graphics interpretation. I'd treat it as its own study track from day one rather than tacking it onto the end of prep — about 25% of my total study time went there, and I think that's about right.
Active daily reading is probably the most underrated part of verbal prep. I did it for 6 weeks before my exam and my critical reasoning scores went up about 12 percentile points. Boring advice but it works.
Data Insights definitely needs its own dedicated study time. I underinvested there and it showed on test day. Multi-source reasoning especially — pulling information from two different sources simultaneously is a specific skill you have to practice, not just understand conceptually.
Going from 485 to 615 in 10 weeks is a strong improvement. What resources did you rely on most for quant? I'm 3 weeks in and not seeing much movement yet.
The quant plateau is real. I hit it around week 5 and it took consciously stopping myself from computing anything until I'd fully mapped the logic before my scores started moving again. Reasoning first, computation second.
Congrats on that jump, that's huge. The one thing that actually moved the needle for me was stop treating quant and verbal as separate subjects and start treating timing as its own skill. I'd get a problem right in practice and think I was fine, but I wasn't tracking how long it took me. Once I started doing timed sets and forcing myself to move on after 2.5 minutes no matter what, my score on full-length mocks jumped almost immediately.
The Focus Edition's shorter format kind of tricks you into thinking you have more time than you do. You don't. If anything the pacing pressure is worse because there's less room to recover from a slow stretch. I'd say don't wait until week 8 to practice under real test conditions the way you did -- getting comfortable with the clock early is honestly the thing I'd go back and tell myself.
First attempt I bombed it. I went in thinking my GMAT classic prep would transfer over and it really didn't -- the Focus Edition weights quant and verbal differently and the DI section caught me completely off guard. I wasn't bad at math, I just hadn't practiced the data insights stuff at all, so I basically threw away that entire section.
Second time I completely restarted my prep and treated it like a different exam. I stopped using old GMAT materials and only used official Focus Edition practice tests, which honestly made the biggest difference. The scoring scale is different too so don't stress when your practice scores look weird at first -- it's not the same 200-800 you're used to seeing. Give yourself more time on DI than you think you need and actually review every single wrong answer, not just the ones you were completely lost on.
