I've tutored hundreds of students through calc, and the same three mistakes come up every single time.

1. Memorizing formulas instead of understanding derivations.

If you can't derive the formula from scratch, you don't actually know it. When the exam twists the problem slightly, you're cooked. Start by understanding why the formula works — the memorization happens naturally.

2. Skipping the algebra fundamentals.

Calculus is 70% algebra. Most students fail integration not because they don't understand integrals, but because their fraction manipulation and factoring is weak. Go back and drill the basics. It's not beneath you — it's the foundation.

3. Passive studying.

Reading through solutions is not studying. You need to work problems cold, with the textbook closed, until you can solve them from memory. Active recall is the only thing that transfers to exam conditions.

If this hits home, TutorArc is built to fix exactly these problems — personalized STEM tutoring that adapts to your gaps and forces active problem-solving. No hand-holding, just real improvement.
