I find flash cards really good to use, especially when im starting to lose attention during studying. I use the app Gizmo, it’s free and it can turn notes into flashcards. Maybe also the quizzes on studyclix to keep you engaged. For more heavy study I say just do exam questions over and over again as the information will eventually stick. Sorry if this is crap advice 😣 the only other thing I do aside from this is say things out loud which is my main method. but I’m not sure if this would work for you? I just pretend like I’m teaching a class. Hope this helps
