Practice all four rounds below — results save automatically to Progress.
Number Sense Round
Fast-paced 80-question, 10-minute pure mental math contest. No scratch work or erasures allowed. Every 10th question (Q10, Q20, ..., Q80) is a starred ±5% estimation problem.
- 80 questions in 10 minutes (600 seconds).
- All work must be done mentally — no scratch paper, calculator, or erasing.
- Every 10th question (#10, #20, #30, #40, #50, #60, #70, #80) requires an estimate within ±5% of the exact answer.
- +5 points for each correct answer; −4 points for each wrong answer OR any skipped question before the last attempted problem.
- Trailing blanks after the final attempted question score 0 points.
- Hit pace checkpoints every 2.5 minutes: Q20 by 2:30, Q40 by 5:00, Q60 by 7:30.
- Never leave an early or mid-paper gap before your last answer — a guess has positive expected value compared to an automatic −4 skip penalty.
- On every 10th question (±5% estimation), round to friendly numbers and verify the number of digits first.
