Success has been achieved in these months. The urgent task is to read the textbook, the derivation of the formula and the examples in the book first. Be sure to think while watching, especially examples, because every example may contain solutions. Then, be sure to prepare a reference book, which is usually used for a round of review. Remember, the explanation must be detailed, and don't buy the kind that is all exercises. You can compare the examples in the reference book, explain and do it yourself, and then find some exercises to consolidate it. In fact, high school mathematics content is not much. trigonometric function

Derivative probability and statistical inequality function and set of conic solid sequence. If you put this work into practice, you can finish learning this book in about two months. It is suggested to spend more time on trigonometric function geometry of function sequence.

Next, you can do simulation questions, from easy to difficult. Then, you can attack the questions appropriately. In fact, your key is to improve yourself every day. Before going to bed every day, ask yourself what progress you have made today, so that you can make rapid progress.
