School Yourself is a mathematics website based on doing math, not on watching an instructor do math. Their unique interactive lessons cover math subjects ranging from algebra, geometry, and trigonometry to precalculus and calculus. As you go through the lessons, their algorithms quietly crunch numbers and figure out where students need help the most, or whether they should breeze right through to more advanced material.
Because of their privacy policy, students should be 18 or older in order to sign up.
