How this quiz works

Estimated time is about 22 minutes — a guide only, nothing stops automatically.
Every question has a Skip button. Skipping is permanent — you cannot come back to it.
Time is recorded question by question and shown in the final report.
Write surds as they are: type √3 or root3, and fractions as -1/2 or √3/2. Do not round to decimals.
Use the θ = 37°, 53° pair from the 3–4–5 triangle: sin 37° = 3/5, cos 37° = 4/5, tan 37° = 3/4.
