I've tutored hundreds of STEM students and the #1 mistake is always the same: passive re-reading.

You highlight your textbook. You re-read your notes. You watch the lecture again. And you still bomb the exam.

Here's what actually works:

Active recall — Close the book and try to solve problems from memory. If you can't, THAT'S where your gaps are.

Spaced repetition — Don't cram. Review material at increasing intervals. Day 1, Day 3, Day 7, Day 14.

Teach it back — If you can't explain a concept simply, you don't understand it. Try explaining it to an AI and see where you get stuck.

This is exactly why I built BrainWave AI. It's an AI tutor that forces you into active learning — it doesn't just give you answers, it walks you through the reasoning step by step.

If you're struggling with calc, physics, orgo, or any STEM course — try it out. Your GPA will thank you.
