GRE, GMAT, LSAT, and MCAT preparation grouped around a single goal: getting into graduate, law, business, or medical school.
Koydo Graduate Prep collects the entrance exams for advanced study — the GRE for graduate school, the GMAT for business school, the LSAT for law school, and the MCAT for medical school — into one goal-based group. Free study guides for the GRE, LSAT, and MCAT are live today, organized topic by topic: quantitative comparison and text completion for the GRE, logical reasoning and reading comprehension for the LSAT, biochemistry and critical analysis for the MCAT. GMAT material is in development. The full experience — diagnostics, adaptive practice, and timed mock exams — is in early access ahead of launch, with an open waitlist. Graduate Prep is built by KOYDO LLC and follows the same rules as every Koydo surface: ad-free, honest about what is live, and organized so working applicants can study in focused sessions.
Every exam product here is coming soon. Free GRE, LSAT, and MCAT study guides are open to read today.
Built for adults
Topic-sized units mean a lunch break or a commute is enough to finish something — no two-hour minimum before progress counts.
Reasoning first
Graduate exams reward reasoning over recall. Every worked answer walks through the logic, not just the result.
Four exams, one place
Deciding between law and business school? The group keeps every graduate-entry exam under one roof, one account, one plan.
