Good ways to cram for an exam? My brain feels overloaded and I just started to study!

Prioritise! Make a list of everything you have to study in order of importance/your weakest to strongest topics, then work your way down the list. Also work out how much time you've got left to study, then divide that time by the number of topics you've got, to work out how long you've roughly got to learn each one, and try to stick to those times
