My experience at that time was to start with the real questions over the years, roughly classify questions, compare series, analytic geometry, trigonometric functions and so on. , and then classified and studied in the form of special topics. If you have a high error rate in a certain category, then do special training. At the same time, take notes when doing the questions, standardize the answers, and develop good writing and rigorous thinking, so that you will have great gains! Finally, I wish you all your wishes! !
