Have an Answer?
Reviewing my notes while they are fresh in my mind always helped me retain information so I did not have to learn everything all over again before an exam. That way I could also get a sense of what the teacher liked to focus on (this could be helpful when it comes to the final). However, I also took notes in my books and textbooks. If you are trying to sell back your textbooks, take notes on index cards and place them in the relevant pages so you can refer to them later.
Do not only repeat information. Ask questions and write down the things that confuse you. Chances are they confuse other people as well and the professor will be glad that you asked a question in class.

Always remember that Questions are more important than answers. Thee would be no research if no one every asked questions. So take your questions seriously!
Here are a few study habits that I have found helpful:
1. ask questions that you are genuinely interested to know about on the test subject
2. be humble and recognize what you do not know
3. it is better to ask yourself basic questions on your own than to not know the answer in front of peers
4. review your notes but even more importantly use your knowledge so that you can remember the ideas effortlessly
This is not a quick way to study for a test. If you study much ahead of time using this method, you are more likely to perform well on exams and to reduce your anxiety.
I hope this helps.
