About OnePrep

OnePrep is an AI-powered preparation platform for the GMAT Focus Edition, built in India for students aiming at top business schools in India and abroad. It diagnoses the exact cognitive skills behind your mistakes and builds a personal path to your target score.

Why OnePrep exists

Most GMAT platforms track topics and accuracy. Those numbers measure progress, but they cannot tell you why your score is stuck or whether you are ready. A student who is "weak at Reading Comprehension" is usually weak at one narrower skill, such as drawing inferences. OnePrep tracks the specific skill that failed on each question, shows how many points it is costing you, and points your practice at it.

How it works

  • Diagnose. A diagnostic test maps your answers to 18 skills across Quant, Verbal and Data Insights.
  • Plan. An AI study plan sets each day's practice and recalibrates as your results change.
  • Practise. 1,500+ questions, sectional tests and full-length mocks, with an AI tutor that explains any question step by step, at any hour.
  • Measure readiness. Session analytics and the OneScore readiness score show whether you are on track for your target score by your exam date.
