To study, you need to be persistent. Review difficult topics. Make sure you have a stack on quizlet that you study as needed. Write paper notes, and ask questions. Asking questions leads to knowledge. Studying is the most important thing you can do. It is the work that you put in, that causes the payoff that you get. You have to approach studying in such a way that you can learn. Turn down conversation, listen to white noise, and dedicate yourself to the current assignment. Do that, and you will pass.
