Baseline and target score
Take a diagnostic and record misses by section, topic, and cause. Set a target score based on your programs, then identify the two sections most likely to move that score.
The GMAT is short enough that every weak habit shows up quickly. The best prep loop is diagnostic, drill, timed set, review, and repeat. Because Data Insights pulls from math, verbal reasoning, and data interpretation, it should not be left until the final weeks.
The 12-week plan
Balance concept work with timed decisions
Quantitative Reasoning foundations
Rebuild arithmetic, algebra, rates, ratios, number properties, exponents, inequalities, and word-problem translation. For every miss, write the setup you should have seen before doing calculations.
Verbal Reasoning foundations
Practice reading comprehension and critical reasoning. Your review should name the wrong-answer pattern: out of scope, too strong, reversed logic, unsupported inference, or answer to a different question.
Data Insights
Work through table analysis, graphics interpretation, multi-source reasoning, and data sufficiency style decisions. Slow down enough to identify what the question is asking before touching the data.
Mixed timed sets
Combine sections in shorter timed blocks. Practice skipping and returning deliberately, not emotionally. Review timing misses separately from concept misses.
First full mock
Take a realistic practice exam. Use the review to decide whether your biggest score lift comes from accuracy, pacing, or section-specific content.
Repair week
Build three repair blocks from the mock: one Quant, one Verbal, and one Data Insights. Redo missed questions after a delay so you test understanding, not memory.
Second mock and final targeting
Take another full practice exam. If a section is stable, maintain it with short sets. Put new energy into the section where your miss log still shows repeated patterns.
Final polish
Use light mixed sets, formula and logic review, and exam-day pacing practice. Avoid brand-new material in the final 48 hours unless it is a tiny, high-frequency gap.
Section strategy
Train the skills the exam actually scores
Quantitative Reasoning
Make setup quality your main metric. Many misses come from translating the prompt poorly, not from difficult arithmetic.
Verbal Reasoning
Practice explaining why four answers are wrong. That habit is especially useful for critical reasoning and inference questions.
Data Insights
Rotate chart, table, multi-source, and data sufficiency tasks early. Data Insights is not just math; it is decision-making under information pressure.
Simple weekly cadence: two Quant blocks, two Verbal blocks, two Data Insights blocks, and one review block that revisits the ugliest misses from the prior week.
