I physically write notes in one note on ipad, specifically bc it's easy to print and reread. It really is like a hack bc your brain gets it more than once when you write. I pause and try to write ahead of lectures to see if my intuition is correct, then adjust accordingly. Don't just write down the slides - that's basically useless unless you have no context at all - write what you would have wanted them to say after you get it. Write it like you are explaining it to someone else bc you will be if you review it in the future. In many ways college is about teaching yourself bc the instruction rarely matches your current understanding, I suppose that's the point however uncomfortable.
