As a teacher, I see students struggle with this all the time. The most effective approach is different for everyone, but research consistently shows that active practice beats passive reading. Don't just read — do problems, write summaries, teach the material to someone else.

There's no one-size-fits-all answer here. Experiment with different approaches and pay attention to what actually works for you, not what worked for your friend. Learning styles are real — some people learn by reading, some by doing, some by listening.

Strunk and White's 'The Elements of Style' is a tiny book that will make you a better writer almost overnight. Every student should own a copy. It's cheap, it's short, and the advice in it never goes out of date.

Don't pull all-nighters. The research is clear that sleep is when your brain actually consolidates what you learned. Studying until 3am and then taking a test exhausted is worse than studying less and sleeping. Trust me, I learned this the hard way.

Go to your professor's office hours. Seriously. Almost nobody does, and the ones who do get better grades and better recommendation letters. Professors WANT to help students who show up and care. It's the most underused resource in college.

The standard advice on this is actually pretty good. But what nobody tells you is that consistency matters more than intensity. Studying 30 minutes every day beats cramming for 6 hours once a week. Build it into your routine.

Flashcards still work. Old-fashioned index cards. Make them yourself — the act of writing the card is half the learning. Quiz yourself, shuffle them, put the hard ones in a separate pile. Low-tech but it gets results.
