How scores are calculated

Every problem is worth up to 1,000 points. You get one answer, and your score depends on if you are right and how fast you were.

Right answer: faster is better

You start with 500 points for being right. Up to 500 more come from speed, and that bonus gets cut in half every 5 minutes.

Close answer: partial points

Some answers are measured values, like a decimal or a number with a unit. If yours is close but not exact, you still earn points. Time does not matter here.
