Build a 90-Day GMAT Focus Study Plan

A GMAT Focus Edition score of 645 puts you in the 87th percentile. That's roughly what an old-GMAT 700 used to be. Getting to that level in 90 days? Totally doable if you stick to a smart, disciplined study plan. It isn't about memorizing facts; it's about focused practice and really understanding the test.

Understand the GMAT Focus Edition Structure

The GMAT Focus Edition, which officially launched in 2026, has three sections. Each section runs 45 minutes and has 20 questions. We're talking Quantitative Reasoning, Verbal Reasoning, and Data Insights. The whole test is just 2 hours and 15 minutes, with an optional 10-minute break in the middle. This shorter format means you've got to be efficient and know these question types inside and out. You need to know what you're up against, period, before you even crack open a book.

Quantitative Reasoning

This section hits your problem-solving skills, digging into arithmetic, algebra, and geometry. You'll see Data Sufficiency questions here, which are unique. They ask you to figure out if the info given is enough to answer a question. Good news: no more Sentence Correction or essay sections like on the old GMAT. The Focus Edition wants to see critical thinking, not just memorized formulas. Start by finding out where you're weakest in these core math areas.

Verbal Reasoning

Verbal Reasoning checks how well you read and understand text, how you reason through arguments, and how you fix written English to be standard. You'll tackle Reading Comprehension and Critical Reasoning questions. Those old Sentence Correction questions? Gone from the Focus Edition. This is a clear shift toward higher-level logic and analysis. So, practice active reading and really breaking down an argument.

Data Insights

Data Insights is the new kid on the block. It blends parts of the old GMAT's Integrated Reasoning with Data Sufficiency from the Quant section. Here, they're testing your ability to look at data from different places and make sense of it. Questions come in all shapes: Data Sufficiency, Multi-Source Reasoning, Table Analysis, Graphics Interpretation, and Two-Part Analysis. This section makes up a full third of your total score, so don't even think about ignoring it. Being good here is crucial for a great score.

Phase 1: Diagnosis and Foundation (Weeks 1-3)

Your first three weeks are make-or-break. They're all about figuring out where you stand and then beefing up your basics. Don't skip this diagnostic step. It sets you up for smart studying.

1. Take a Full-Length Practice Test: Grab an official GMAT Focus practice test from mba.com and take it under strict timed conditions. Don't worry about the score right away; it’s a tool. It'll show you exactly where you're strong and, critically, where you're weak across all three sections. PrepGuin's adaptive drills can help you personalize this.
2. Analyze Your Results: Go over every single question from that practice test. If you got something wrong, figure out why. Was it a content gap? Did you run out of time? Did you misread the question? Was it just a silly mistake? PrepGuin's Mistake Vault helps you tag these errors for later review.
3. Review Core Concepts: Your diagnostic will highlight what you need to work on. Spend time revisiting fundamental math ideas (arithmetic, algebra, geometry) and any grammar rules you're shaky on. Use PrepGuin's Guided Roadmap to ensure you're hitting all the right topics. Don't just watch videos; do practice problems after each concept.
4. Set Score Goals: Look up the average GMAT Focus scores for your target business schools. Top programs, like London Business School or INSEAD, often look for scores above 655. Based on your initial score and your ambition, decide on a realistic target. Jumping 100 points in 90 days is totally possible with consistent effort.

Phase 2: Targeted Practice and Strategy (Weeks 4-9)

This is the serious part: applying what you've learned and sharpening your test-taking approach. Consistency is key for these six weeks.

Weekly Breakdown

Here's an idea for structuring your week. Swap between sections to keep things fresh and avoid burnout.

Day	Focus Areas	Practice Format
Monday	Quantitative: Algebra & Geometry	20-30 timed practice questions
Tuesday	Verbal: Reading Comprehension	2-3 passages with questions, untimed analysis
Wed.	Data Insights: Multi-Source & Table	10-15 timed practice questions
Thursday	Quantitative: Number Properties & Data Suff.	20-30 timed practice questions
Friday	Verbal: Critical Reasoning	15-20 timed practice questions
Sat.	Review Week's Mistakes / Sectional Drill	Check Mistake Vault, 45-min section drill
Sunday	Rest / Light Review	Quick review, plan for next week's studies

This table is just a suggestion. Adjust it based on your personal strengths and weaknesses from Phase 1. If Data Insights is really kicking your butt, put more time into it.

Deep Dive into Question Types

Don't just practice aimlessly. Understand the method for each question type.

• Quantitative Reasoning: For Data Sufficiency, learn to check statement 1, then statement 2 alone, then both together. For regular problem-solving, spot common traps and find the fastest way to solve.
• Verbal Reasoning: Practice active reading for Reading Comprehension. For Critical Reasoning, get good at figuring out an argument's structure: premise, conclusion, assumption. PrepGuin's Ask Athena feature can clarify specific question types.
• Data Insights: You need to be comfortable with all sorts of data displays here. Work on quickly pulling out key info from graphs, tables, and different tabs. Get efficient at combining info from various sources.

Review and Adjust

All through this phase, regularly go over your wrong answers and the questions that stumped you. Use PrepGuin's Mistake Vault to see patterns. Are you bombing fraction questions? Or stumbling on inference questions in Verbal? Shift your study plan to give those areas more attention. Reviewing consistently is just as important as practicing consistently.

Phase 3: Refinement and Peak Performance (Weeks 10-12)

These last three weeks are for tying everything together, mastering your timing, and building up your endurance. You want to be at your best on test day.

1. Full-Length Practice Tests (Weeks 10 & 11): Take one full GMAT Focus practice test pretty much each week. Do it under real exam conditions: no distractions, timed breaks, just like you'll be at the test center. The official MBA.com practice tests are perfect for this. Review them thoroughly afterward.
2. Focus on Timing: With these practice tests, really pay attention to your pace. Are you spending too long on certain questions? On the GMAT Focus Edition, you get about 2 minutes and 15 seconds per question. Learn when to cut your losses and make an educated guess. Don't aim for perfect accuracy if it means running out of time later.
3. Review Mistake Vault: Schedule dedicated time to review every single error you've logged in PrepGuin's Mistake Vault. Try those questions again. If you still get them wrong, go back and review the underlying concepts. This focused review makes sure you don't keep repeating the same mistakes.
4. Strengthen Weakest Areas: Don't try to get everything perfect. Instead, focus on boosting your remaining weak spots. A few extra points in a struggling section can do more good than tiny gains in an area you're already strong in. Use PrepGuin's Adaptive Drills to target those specific topics you need to improve.
5. Simulate Test Day: Practice your ideal test-day morning routine. Eat the same breakfast. Drive the same route to your practice test spot (even if it's your desk). This helps reduce anxiety and makes the actual day feel familiar.
6. The Week Before: The last week is for light review, nothing intense. Skim notes, do a few warm-up questions. Get plenty of sleep, eat well, and keep your stress down. You've prepared. Trust it.
