I'm a very strong visual learner and decent at auditory learning. The problem I usually have is I'm able to remember almost every diagram in the textbook, lecture slides, study notes and labs. The problem is it often becomes a jumble in my head and when I begin to formulate the answer, it's always detailed but I have a tendency to focus on some of the details too much and don't give a complete answer to the question.

The way I got around this problem, especially for biology, was to create a lot of flow charts and memorize each. I'd then either draw out or work out in my head the ways in which the flow charts are connected to one another. When I studied, I ask myself what would happen if abc changed instead of def.

For math, I used a similar method. For some of my courses, I had to know the derivations of formulas, so I'd memorize them and see how I could derive additional formulas. I'd also write out then memorize examples of problems word-for-word and the steps needed to solve the problem. In this sense I created numerous mental templates and each time I was faced with a math problem, I'd run it through the various templates to see which it matched. In the cases when it didn't match any one template, I'd see which elements of relevant templates matched, think (or write out) how I initially got to them, then combine it all together to solve the problem.

The point I'm making for each is that once you recall a portion of the template or flow chart, generally you can recall the rest word-for-word or derive it. The next step is to create new ones for each problem, which is of course the hard part so start with easy practice questions then move your way up. Eventually, you may find there's something you don't understand or your solution is incorrect. This is a red flag that you need to review this particular concept. For me, I'd keep a sheet or two of paper that had notes on each concept I was having trouble with. Once I felt confident I knew it, I'd put a check-mark or cross it out but still keep the paper with me in case I had to review something.
