About

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

1
The problems are public — we organize and credit them properly.

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.

2
Every answer is tracked — not just scored.

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.

3
Weaknesses are surfaced, not hidden.

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.

4
Parents are kept in the loop — automatically.

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.

5
Daily habits beat last-minute cramming.

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:

🔁
Active Recall over Passive Reading. Answering questions is ten times more effective than re-reading. Every session is active practice.
🎯
Targeted Practice over Random Drilling. Practice your weak topics, not just your comfortable ones. Data-driven focus beats volume.
📅
Consistency over Intensity. 20 minutes every day beats 3 hours on weekends. We build the habit, not just the score.

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.
