Overview
The preset math tests decide what you practice; this one lets you decide. You are not just the test-taker, you are the test-maker: choose which operators to drill, set the number ranges you are comfortable with, decide how many questions include decimals, mix in fractions, and pick any duration up to 15 minutes. The tool then generates a personal stream of questions to solve before the timer runs out. Use it to isolate exactly the weakness a preset test exposed, whether that is dividing decimals or adding large numbers under time pressure.
Game Phases
1
Build your test
Pick a duration, enable the operators you want to train, and tune the number ranges, decimal share and fractions to your level.
2
Generate and start
The tool generates roughly one question per second of your chosen duration. Press start when you are ready.
3
Solve the stream
Answer a question and the next one appears immediately. Type your answer or use the on-screen keypad on mobile. No calculator; feel free to use pen and paper.
4
Review your results
After the timer ends you see every question with your answer, the correct answer, and your average solving time per operator and question type.
Scoring
+1
Correct answer
Each correct answer adds one point.
-1
Wrong answer
Each wrong answer subtracts one point, so accuracy matters as much as speed.
Your score is correct minus wrong answers within your chosen duration, the same rule the preset math tests use. Because you set the difficulty yourself, scores are personal: compare runs against your own earlier attempts with the same settings, not against a leaderboard. The results screen breaks down your average time per operator and per question type so you can see exactly where to focus next.
