At the beginning of every week in a semester, I usually contemplate and organize what will be my goal or what I want to attain at the end of the semester. In this way, I can try out different study tools that may work for me. Every class has different approach and topics, so there would be a variety of ways to make it easier to comprehend and learn. Examples of the study tools I use are flashcards, or I create my own tests. Hope this answer helps.
