About
Honest prep, built to be trusted.
Keiko Study is an independent test-prep platform for the tests that decide where you go next — the GRE and its subject tests, and the GMAT. Public study content is free and cited; accounts, practice, and payments are separated behind server-side checks.
What we stand for
Source-backed by default
Published exam facts and technical concept claims identify official exam documentation or an open textbook on the page. Product status is labeled separately.
Checked on the server
Practice answers are validated in a server function. The correct answer never reaches your browser before you submit.
Calibration over hype
We compare explicit confidence ratings with correctness from your own checked attempts. That evidence is not presented as an exam-score forecast or outcome promise.
No fabricated proof
No fake reviews, no borrowed benchmarks, no numeric outcome promises. Progress is computed only from your own attempts.
Where things stand
GRE Physics is the primary in-depth track. Other GRE and GMAT hubs are limited overviews; reviewed notes and question coverage vary by exam. Account practice is server-checked, while Pro tutor access still depends on entitlement and provider availability.
