About StemDriller

StemDriller is a site that generates practice problems, with answers, for STEM subjects.

I made it because practicing is the most effective way to study, and I couldn’t find a good place to just do that. I’d finish a video online and want to practice what I’d just learned, but they only gave a few problems and I needed more. Worksheets slow everything down, and flashcards can’t generate a new problem every time. I didn’t need explanations or another way of having something taught to me. I had my class notes for that. I just wanted the problem and the answer, so I could tell right away whether I got it right.

It started out as MathDriller, because math was the subject I needed it for most. Then I took chemistry and realized the same idea worked there too, so it grew into StemDriller.

StemDriller doesn’t teach the material. If you get something wrong, your notes, a video, a textbook, or your teacher can explain why. Reference sheets are there on the side if you want them, but they’re optional.
