About STEMinute

STEMinute is a daily set of short STEM problems in physics, math, chemistry and electrical engineering. Every day, each subject gets a new round of three problems, from easier to harder.

Why it exists

We wanted a quick, honest way to practice science and math every day: a few minutes, one clear answer per problem, and no tricks.

How it works

You type an answer and the site checks it. The faster you are right, the more points you get. The answers are never sent to your device while a round is open. When a day ends, its problems move to the archive of past problems, where you can read the answers and the main steps.
