MugenPrep was built by a parent who noticed a gap. Not in the number of practice problems available — there are plenty of those. The gap was in what happens around the problems.
Past AMC 8 problems are freely and publicly available through the Mathematical Association of America and Art of Problem Solving. Any student can find them. The hard part isn’t finding problems — it’s knowing which ones to practice, understanding why you got them wrong, and actually improving over time.
“We don’t make learning easier. We make struggling more effective.”
What MugenPrep actually does
All AMC 8 practice problems on MugenPrep come from official past competitions, used with credit to the Mathematical Association of America (© MAA). We don’t claim ownership of the problems — we build the system around them.
When a student answers a problem, MugenPrep logs it against topic (algebra, geometry, number theory, probability) and difficulty level. Over time, this builds an accurate picture of exactly where they’re strong and where they’re losing points.
The dashboard shows topic-by-topic accuracy in plain language: strong, needs review, or weak. No vague progress bars — just clear data. A student who is 87% accurate in algebra but 41% in geometry knows exactly where to focus.
Every week, parents receive a concise email report: how many days their child practiced, how many problems they solved, their overall accuracy, and which topics need the most attention. No nagging required.
MugenPrep is built around daily practice — short, focused sessions that build real pattern recognition over weeks and months. Streak tracking creates accountability. The daily problem creates the habit.
Our Philosophy
Three principles guide everything we build:
Starting with AMC 8
MugenPrep launched with AMC 8, 10, and 12 math competition prep. More is coming — AP courses and SAT prep — all built on the same foundation.
