Two weeks ago we were talking about exposure and how it's critical to the learning process, and how we need to give our brains time to rest
I had an exam to study for in my operations management class. Instead of studying relentlessly for several days and cramming as much as I could, I would study for an hour and a half max and then not do anything for an hour. I slept a lot at night time. I did this for 5 days before the exam, studying way less than usual by about 25-30%, and got one of the highest scores on the test.
Thylias' method works.
