Everyone already hit the nail on the head. Biggest thing for me, and what I usually preach to everyone, all nighters dont work, and when you're tired, stop studying. You dont retain information when you're tired, theres no point in going on. Especially the night before a test/checkride. If you dont know something by 10pm the night before, you arent going to learn it. Give your brain a rest, and you'll retain what you know that much better. I always made it a point to just relax for a few hours before bed, the night before a checkride. Theres so much information to absorb there, and you can only learn so much. Knowing where to find things is sometimes more important than the information itself.
Do what works for you. We had guys who just read stuff once and it stuck, others made thousands of quizlet cards (this dude was the real bro of the flight), others who hand wrote flash cards. Everyone is different man. We'd quiz each other on road trips to Austin or wherever we were going.
