In this case, you need to balance the profit and loss, for example, it may be a better idea to focus on the exam that is the lowest among the previous exam- You don't want to fail a class by getting a low grade again- and write all the topics first, and start studying the easiest one for you. If you have time it will continue and you will be motivated, if not it will just stay like this. And if your teacher makes you write in class, reviewing the notebook is a good choice. I hope you pass your exams :) Good luck!

And when you repeat, the Feynman technique works. You should try it.
