Mathimus™ AI Coach

Hints first

Inside the App

Everything a student needs to prepare

Real screens from Contest Math Pro on iPhone and iPad, with an Apple Pencil scratchpad on every problem.

Practice Arena: a suggested next step from the student's own results, 70 full mock exams, and timed practice sets — **Practice Arena**Full exams and timed sets, with a suggested next step from the student's own results.

A geometry question from a full practice exam, with a diagram of rectangle ABCD and a cross-out mark on each answer choice — **Contest-style questions**Five choices to pick or cross out, real timing, and clear diagrams where they help.

Mathimus gives a geometry practice problem with tappable answer choices A to E; students tap, they don't type — **Mathimus AI coach**Explains the idea, then hands the problem back to the student.

Mistake Bank: missed questions to fix, grouped by reason and topic, each showing the student's answer and the correct one — **Mistake Bank**Missed test questions are saved with the trap the wrong answer points to. Solve a new version on your own and it's fixed.

Student progress: the days left until the AMC 8, an estimated score with its likely range, and accuracy by topic — **Progress**Accuracy by topic and an estimated score range once there's enough practice.

Parent Dashboard: the PDF progress report, this week's practice, the days left until the AMC 8, and the student's progress overview — **Parent Dashboard**Free for every family, with a printable PDF report.

On iPad

More room to work it out

The same app on iPad, with bigger diagrams and an Apple Pencil scratchpad on every problem: sketch the figure, write the work, erase and undo. On a 13-inch iPad, or any iPad held sideways, the scratchpad sits beside the question during a test. Parents get the full dashboard and PDF report on the larger screen.

Contest Math Pro on iPad: a full practice exam question with a polygon drawn on graph paper, five answer choices, and the scratchpad beside it — **Contest questions, bigger diagrams**Full practice exams with clear figures, and the scratchpad beside the question.

AI Coach

Meet Mathimus™

When a student is stuck, Mathimus gives a hint and asks the next good question, so the breakthrough is theirs.

Hints first, so the thinking stays with the student.

Mathimus sees the problem the student is working on, including its verified answer and solution, so its help fits that exact question. It points to the next step, explains the idea behind it, and asks a question the student answers with a tap.

One step at a time: hints point to the next step. Mathimus won't state the answer until the student has answered or finished the test. Then it can walk through the full solution.
Practice on demand: ask for a similar problem with new numbers to lock in the idea.
Built for middle-school students: a parent turns the coach on, every reply is safety-checked, and conversations stay on math.
No typing to the AI: students tap guided buttons and A–E answer choices — there's no text box, so nothing a student writes can reach the AI service.

Like any AI, Mathimus can make mistakes, so students are encouraged to check the math.

Sample AMC 8®-style problem

"In right triangle ABC, the legs are AB = 6 and BC = 8. A circle is drawn inside the triangle, touching all three sides. What is the radius of the circle?"

Hint 1 • Get your bearings

"Start with what you can find right away. How long is the third side, AC? Then, what is the triangle's area?"

Hint 2 • See the idea

"Draw lines from the circle's center to the three corners. That splits the big triangle into three smaller ones, each with height r. Can you write each small triangle's area using r?"

Hint 3 • Put it together

"Add the three small areas and set the total equal to the area you found in Hint 1. Which number is left to solve for? Work it out, then pick your answer."

What's Inside

538 practice tests across the main AMC 8® topics

70 full exams (25 questions, 40 minutes), the diagnostic placement test, and 467 shorter timed sets matched to each part of the contest: Q1–10 speed sets, Q11–17, Q18–22 and Q21–25 challenge sets. All 16,000+ problems are new, written to practice the same skills and ideas the AMC 8® tests, and come with step-by-step solutions.

Shapes, Area & Angles

Areas of composite figures, similar triangles, the Pythagorean theorem, circles, angle chasing and 3-D solids, with diagrams where they help.

Pythagorean Theorem

Similar Triangles

Composite Areas

Angles in Polygons

From a full practice exam

Triangle Inside a Rectangle

In rectangle ABCD, AB = 12 and AD = 6. Point M is the midpoint of side BC. What is the area of triangle BAM?

Common trap: using all of side BC (6) as the height gives 36. The height is BM, which is only half of BC.

Divisibility, Primes & Remainders

Prime factorization, divisibility rules, GCD and LCM, remainders and repeating patterns, digits and factorials.

Prime Factorization

Divisibility Rules

Remainder Patterns

GCD & LCM

Sample problem

Trailing Zeros

What is the smallest positive integer n such that n! ends in exactly 10 zeros?

Common trap: counting only the multiples of 5. Multiples of 25, like 25 itself, each add an extra zero.

Equations, Patterns & Rates

Linear equations, fractions, ratios and percents, number patterns and sequences, factoring tricks, and rate, time and distance word problems.

Ratios & Percents

Difference of Squares

Rates & Distance

Telescoping Products

Sample problem

Telescoping Product

Evaluate (1 − 1/4)(1 − 1/9)(1 − 1/16) … (1 − 1/100).

Shortcut: write each factor as (1 − 1/k)(1 + 1/k). Most terms cancel, and the product falls out in under a minute.

Counting & Probability

Careful casework, counting the complement, arrangements, grid paths, and probability with dice, coins and spinners.

Complementary Counting

Grid Paths

Arrangements

Probability

Sample problem

Seating With a Restriction

In how many ways can 5 students sit in a row of 5 chairs if Alice and Bob refuse to sit next to each other?

Shortcut: count all seatings, then subtract the ones where Alice and Bob sit together. It's much faster than listing cases.

Speed & Accuracy

Questions 1–10 reward quick, careful work. 140 Q1–10 speed sets and free daily speed drills build pace, and the Gym adds quick formula and mental-math practice.

140 Q1–10 Speed Sets

Daily Speed Drills

Mental Math Shortcuts

Fractions & Percents

Sample problem

Mental Difference of Squares

Compute 105² − 95² without multiplying out either square.

Shortcut: a² − b² = (a − b)(a + b), so this is 10 × 200 = 2,000. A few seconds instead of a minute.

Mistakes That Teach

See the trap behind each wrong answer

Every wrong choice on a CoMP test has a known trap behind it. When a student picks one, the app shows the trap it detected. Questions missed on practice tests and the Problem of the Day go to the Mistake Bank and come back with new numbers to retry; the hardest ones wait until the student's level in that topic catches up.

🧠

Concept Gaps

An idea or formula the student hasn't learned yet, like an area formula or a divisibility rule.

Fix: solution walkthrough & coach

✏️

Careless Slips

The right approach with an arithmetic or sign mistake along the way.

Fix: speed drills & checking habits

👁️

Misreads

Solving for the wrong quantity, like x instead of 2x + 1, or missing a word like "not" or "positive".

Fix: retry it as a new problem

⏱️

Rushed Guesses

A wrong choice that a quick estimate or guess lands on, like a number that only looks about right.

Fix: timed sets & pacing review
