Practise the quick calculations that slow students down in UCAT QR: percentages, ratios, fractions, unit conversions and everyday arithmetic. Start without pressure, then add a timer when you are ready.
Choose the question types you want to drill. Use untimed practice for accuracy, or add a timer when you want UCAT-style pressure.
Use this as a free online mental maths trainer for fast arithmetic practice, especially if you are preparing for UCAT Quantitative Reasoning. UCAT QR gives you roughly 40 seconds per question, including the time to read the stem, interpret any data and do the maths.
Practice mode is for building speed calmly: choose your question types, difficulty, timer and session length, then drill the areas that need work. Timed practice rewards fast answers, while untimed practice helps when you want accuracy first.
Ranked mode is for short, focused pressure. You get 3 minutes to answer as many questions as you can, and the run ends early if you make 3 mistakes. Your best ranked score is saved on your device, and you can add a name if you want the score to appear on the public leaderboard. The UCAT calculator is available when needed, but using it reduces the question score by 20 points in timed or ranked mode.
Every question type in this trainer is one of the quick arithmetic skills that shows up in real UCAT QR questions. The same drills also help with general mental maths fluency: percentages, ratios, fractions, conversions, averages and core operations. Tables and graphs are intentionally excluded, since those are best practised in full timed UCAT mocks; this tool sharpens the arithmetic underneath.
Yes, completely free. There is no sign-up, no account and no payment. Your settings and personal best are saved in your own browser only.
Ranked mode is a quick 3 minute challenge. Keep answering until the timer finishes or you make 3 mistakes. Your best score stays on your device, and adding a name is only needed if you want to appear on the public leaderboard.
Yes. It is built around the arithmetic skills that matter for UCAT QR, but the practice is also useful for anyone who wants to get quicker at percentages, fractions, ratios, unit conversions and mental arithmetic.
A QR question bank tests the full skill: reading the stem, interpreting data, then doing the maths. This trainer isolates the maths step so you can build fast arithmetic without burning through scarce QR practice questions.
Short, frequent sessions beat long ones. 10–15 minutes a day for 4–6 weeks before your test will produce a noticeable speed gain. Pair it with at least one full timed UCAT mock per week.
Hard mode pushes the numbers past what most people can multi-step in their head reliably. Drop back to Medium and target question types where your accuracy is below 70%; that is where speed gains come from.
No. Mental maths is one part of UCAT QR; the rest is question-type strategy, time management and pattern recognition across all four subtests. If you want structured 1-on-1 preparation across the entire UCAT, take a look at our UCAT Preparation Course.
