Math Ace: Contest Math

Cyquila LLC

About this app

Math Ace is a complete practice library for the AMC 8, AMC 10 and AMC 12 mathematics
competitions — 95 contests and more than 2,300 problems with step-by-step solutions, all
of it available offline.

WHAT'S INSIDE
• AMC 8 — every contest from 2007 to 2026
• AMC 10 — both the A and B contests, 2007 to 2025
• AMC 12 — both the A and B contests, 2007 to 2025
• Step-by-step solutions written for Math Ace, with every count and every case shown
• Every diagram and figure from the contest

FOUR WAYS TO WORK
Plan — say when you sit the contest and how often you can work, and Math Ace writes a
session-by-session schedule: the lessons first, then practice that climbs in difficulty —
warm-up questions, then core, then challenge — and only then full timed papers, the most
recent saved for last. Regular reviews of what you got wrong throughout, and sessions tick
themselves off as you complete them.

Reinforce — one question at a time, checked the moment you answer, with the solution
immediately underneath. Draw from every paper, a single paper, your bookmarks, or the
questions you most recently got wrong.

Exam — the real thing. Choose the paper by year (and A or B), see how it is scored, and
sit it against the clock: 40 minutes for AMC 8, 75 for AMC 10 and 12, adjustable if you
want a shorter practice run. Move with previous and next, jump with the answer sheet, and
nothing is scored until you submit. You can also read any paper through without the clock.

Material — a short lesson on every topic each contest covers. Every past problem is sorted
into a problem type, and each lesson takes its types in turn: how to spot one, how to solve
it, how often it comes up and where in the paper, and a real past problem worked through.
Then practise the whole topic or a single type. AMC 12 adds logarithms, trigonometry,
complex numbers and recursion to the AMC 10 topics.

SCORED THE WAY THE REAL TESTS ARE
AMC 10 and 12 award 6 points for a correct answer and 1.5 for one left blank — so an
unanswered question is worth more than a wrong guess. Math Ace scores exactly that way and
tells you before you start, because it changes how you should take the test. AMC 8 is one
mark per correct answer with no penalty, and is scored that way too.

BUILT TO STAY OUT OF THE WAY
• Works entirely offline — no account, no sign-in, nothing to set up
• Mathematics is properly typeset, not screenshots, so it stays sharp at any size and
follows your font size setting
• Full dark theme, including the diagrams
• Phones, tablets and Chromebooks, with a sidebar on larger screens
• Your practice history stays on your device and is never sent anywhere

What’s new

Fixes from a full check of every problem:
• 2026 AMC 8 Problem 11 now has its figure, answer choices and a worked solution, and Problem 23 shows its figure.
• Tables in a few problems read correctly, and prices show their dollar signs.
• Words in a problem no longer link out of the app, so a stray tap can't interrupt an exam.
• Cleaner one-line previews in problem lists.
