Most students study the night before an exam completely wrong.
They highlight. They re-read their notes. They flip through flashcards passively.
And then they walk into the exam confused about why nothing came back.
Here's what cognitive science actually says.
A massive review of study techniques by John Dunlosky found that highlighting, re-reading, and summarising are all rated low utility. They feel productive but produce almost no real learning.
Why? Because they build recognition, not recall. Exams test recall. You've been training for the wrong event your whole life.
The fix is one method called retrieval practice. Close your notes. Write down everything you remember on a blank page. Check the gaps. Repeat.
One study found students who tested themselves three times remembered significantly more a week later than students who read the material four times.
Same material. Less reading. Better results.
I broke down the full brain science playbook in my new ebook 'What Nobody Taught You About Studying' and the memory side of it in 'The Memory Reset.' Both are linked in the comments.
