About GREKMF
GREKMF is an online GRE question bank. We sell timed, exam-like practice with original explanations, skill labels, and performance feedback — not a subscription that renews in the background.
Who operates GREKMF
GREKMF operates the website at grekmf.com and the practice app at app.grekmf.com. Student and institutional support is handled at [email protected]. For licensing, billing, refunds, or content issues, use that address or the contact form.
What the question bank contains
The bank has 8,172 published Quantitative and Verbal practice questions across seven series, including full-length tests with GRE-style section structure. The questions are largely drawn from publicly available GRE sources. GREKMF’s original work is the instructional layer on top: explanations, skill taxonomy labels, analytics, and the practice interface. The KMF 1000 Quant series is free on every account.

Who writes the explanations
Every explanation on GREKMF is written in-house. We do not paste publisher answer keys. The goal is step-by-step reasoning you can reuse on the next variant of the same skill — not a one-line restatement of the correct choice.
How the skill taxonomy and feedback work
Each question is tagged with a domain and a unit from a 200+ label taxonomy covering Quant topics and Verbal question types. You can filter practice to a single skill. After a session, the platform computes accuracy by tag, tracks trends across sets, estimates GRE-scale scores on full tests, and logs misses so you can record whether an error was a misread, a calculation slip, or a concept gap.
Free tools
Alongside the paid bank, GREKMF publishes free browser tools: GRE Vocab Mountain, an on-screen calculator, score and questions-missed calculators, a Quant/Verbal diagnostic, an essay timer, and a test-day countdown. See Free GRE Tools.
