I've only took some practice questions in some free options in mbadotcom and just purchased practice questions which I'm gonna finish my this week
I always get 100% on quant (yes I'm asian lol) and around 80% on verbal, 60% in di section... which seems to be my weakness
I definitely have no time to go through the entire OG guide, I'm planning to go through TTP + GMAT Club Questions + Official Practice Tests while revising my weaknesses topic by topic.
Please share any advice for short-termers! I’d love to hear how other shorties are doing!!

A month is tight, but with your quant foundation you're actually in a better starting position than a lot of people. Here's some honest advice from our end.
Scoring 100% in Quant on practice questions is a great sign that your fundamentals are solid. Just a heads-up though, the GMAT Focus quant section tests those same concepts in tricky, time-pressured ways that can feel very different from standard practice sets. Data Sufficiency questions in particular (which live in the DI section) trip up a lot of strong math students because they test
whether you can solve something, not the solution itself. Don't skip quant review entirely. Just prioritize the question types and pacing strategies over relearning content.
DI at 60% is where your biggest gains areDI is the section most students underprepare for because it's newer and less intuitive. It includes five question types: Data Sufficiency, Two-Part Analysis, Multi-Source Reasoning, Table Analysis, and Graphics Interpretation. Each requires a slightly different skill set, so "study DI" isn't specific enough. You'll want to identify which of those five types are dragging you down and attack them individually.
Our GMAT course covers DI across 17 chapters with 1,300+ practice questions specifically designed for these question types. If you're using TTP, the study plan can be customized to prioritize DI so you're not spending precious time on topics you've already mastered.
With one month, here's the approach that tends to work best for students in your position:
- Week 1: Take an official GMAC practice test (mba.com has them) to get a real baseline — not free question accuracy, but an actual adaptive score. Review every wrong answer aggressively. Identify your 3-4 weakest topic areas.
- Weeks 2-3: Targeted topical study. Focus 60% of your time on DI (your weakest section) and 40% split between verbal weak spots and quant pacing. For each topic, learn the concept, practice untimed until accuracy is very high, then layer in timing.
- Week 4: Take 2 more official practice tests spaced a few days apart. Between them, do targeted review of whatever's still shaky. Go through test-day strategy material. Don't cram new content in the final few days.
One thing to reconsiderYou mentioned having no time for the OG. That's fine, but make sure you're taking the official GMAC practice tests (not third-party mocks). Those are the only ones that use the real GMAT scoring algorithm, and they're the most reliable predictor of your actual score. You can grab the starter kit free from mba.com.
Good luck, you've got this!
