OlymCraft: Math Olympiad Prep

OlymCraft helps primary-school students practice math olympiad and competition problems — with real exam timing and step-by-step solutions that actually teach. Built for parents who want more than a quiz app: your child solves the same kinds of problems as real math contests, then reviews every question to see exactly why an answer is right or wrong. WHY PARENTS CHOOSE OLYMCRAFT • Real exam format — a countdown timer and a full-length "real exam" mode, just like the contest. • Start short, build up — begin with quick 15-minute sessions (8 questions) and work up through 30 and 45 minutes to the full real exam, so primary-school students get comfortable and build skills step by step, without pressure. • Learn, don't just test — every question has a detailed, step-by-step solution. • Track progress — see how much your child has practiced and improve a little every day. • 6 languages — English, Bahasa Melayu, Bahasa Indonesia, Thai, Traditional Chinese and Vietnamese. • Illustrated questions — hundreds of visual problems for real understanding. • Safe and focused — no ads, no distractions. TOPICS YOUR CHILD WILL PRACTICE • Word problems and logical reasoning • Mental math, arithmetic and number sense • Number patterns and sequences • Counting shapes, squares and line segments • Geometry and perimeter • Combinatorics — counting possibilities • Age, calendar and grid-path puzzles HOW IT WORKS 1. Choose the contest, your child's grade, the round and a practice length (15 / 30 / 45 minutes, or a full "real exam"). 2. Pick the question language. 3.
