Tip 1: Memorizing important formulas
In some countries, students are given the flexibility to bring in a cheat sheet, usually a small note card whereby students can jot down important formulas, saving them time in having to memorize too much all in crunched period of time. So, if you’re given the option to bring in a cheat sheet into class, then please do take advantage of that, write out all the formulas and key points and it will definitely bring you good relief.
However, this is not true for some countries. Students are expected to have it all memorized and if that is the case, write out all the formulas pertinent to your exam ahead of time and take time in reviewing them on a daily basis. This would definitely be beneficial for you and also lessen the stress factor.
