Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.

Real feedback from RMMT candidates on Reddit.
"put this off for like 3 weeks then crammed the lateral run out labs the weekend before. glad i did bc that was half the hands on portion. passed first try, still kinda surprised tbh."
"honestly went in pretty skeptical since ive done enough of these certs to be jaded. the mistake review feature actually showed me i kept messing up the pro-cut specs section, fixed it before the real exam. rmmtexam.com was worth setting up an account for."
"studied on lunch breaks for a month, wasnt sure id retain any of the lathe maintenance stuff since my shop barely touches that. the practice questions kept hitting it over and over so it stuck. definately helped more than just reading the manual."
