Highlighting and re-reading your notes feels productive. The research says it barely works. Here's what cognitive science actually shows helps you learn, and how to handle the stress that piles up around all of it.
Why cramming doesn't actually work
Studying the same material spread across several sessions (spaced practice) beats cramming it all into one sitting, even when the total time spent studying is exactly the same.1 Five hours the night before a test teaches you less than one hour a day for five days.1
The other half of it is retrieval practice: actually trying to recall information from memory (like with practice questions or flashcards) rather than just re-reading it. Every time you pull a memory up from scratch, it gets strengthened and easier to access next time.2 Combined, spaced practice and retrieval practice reinforce each other more than either does alone.2
In practice: Instead of one long study session, quiz yourself on the material a day later, then again a few days after that. Closing the book and trying to recall the answer is doing more for you than reading the page a fourth time.
Managing the stress part
Research on stress-management programs for students points to a consistent set of techniques that actually move the needle: structured relaxation training, cognitive behavioral techniques (basically, noticing and challenging unhelpful thought spirals), time management skills, and leaning on social support instead of white-knuckling it alone.3
These aren't just feel-good suggestions. Studies measuring their actual effect found small-to-medium but real improvements in students' ability to handle everyday stress, and better results when practiced consistently rather than as a one-time fix.34
