How to do mathematics, there are so many questions. If you want to get high marks, you must first be familiar with the types of questions, and at least know the theorems and formulas in the book. If it is a college entrance examination question, some questions
It is necessary, such as probability and distribution table, conic curve, trigonometric equation, series,,, you don't want to do a set of problems to analyze, such as steps, scores, difficulty. The most important thing is to look back at the textbook without doing a set of questions. Furthermore, when making a choice, some problems should be done with special values, such as inequality and sequence problems (in the blank), and two or three items can be brought in to test, so that general items can be obtained, and some problems should be combined by drawing and numbers and shapes.
Sometimes the last one or two of the fill-in-the-blank questions and multiple-choice questions are not completely worked out (unless you are particularly good at math). You can guess by excluding one or two items, and then simply give up (guess one). The last one or two big questions are often the finale questions, which are not done systematically at ordinary times and cannot be done in the examination room.
Only a sophomore? As long as you do it systematically, your grades will come up.
It often takes only one holiday to improve math, really! I usually listen to the teacher in class. Study systematically on your own during the holidays. If you have high autonomy, you often don't need a tutor. Do 38 sets and do it seriously. I believe you can do it.
