One of the learning techniques I will use is flashcards. As you know, in every educational course, there is that element of "learning facts" or things "I have to know for the next test". Now, when I study, I flip things in my minds eye. If I were the one making the test,...what are the key things I would want my student to know? If I assign reading of chapters 2 and 3 of this textbook,...and were to test my students,...what kinds of questions would be on that test? If you approach your learning from that perspective, I think you will have a better understanding of the "course objectives" and "key points". It's been my "go to" whenever tackling a complex topic, even when I am not in school,...it could be simply a learning tool regarding a "special interest", as well.
I purchase those stacks of "index cards" and write down my questions on one side, the answer on the other. Each time you study, make 5-10 new flashcards. Once you have your flashcards, you can carry them around with you, and you can flip through them quickly,...it could be a few times a day,...repetition,...and eventually you will have committed this knowledge to memory.
I had stacks of flashcards for each course. Some 35-40 years later,...I still remember them and I haven't looked at them at all,...that knowledge just taking up space in my head.
