Form a study group, but a small one — three or four people max. Explaining something to a classmate is the best way to find out whether you actually understand it. Just make sure it stays a study group and doesn't turn into a hangout.

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.

Break big assignments into small chunks with their own deadlines. 'Write a 20-page paper' is paralyzing. 'Write one paragraph today' is doable. The hardest part of any project is starting, so make starting as small and easy as possible.

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 It's cheap, it's short, and the advice in it never goes out of date.

I graduated college 5 years ago and wish I'd known this earlier: the specific knowledge you learn matters less than learning HOW to learn. Develop good study habits and critical thinking skills and you can adapt to any subject or career.

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.
