In the first round of math review in senior three, many examples can't be done, but the tutorial book has no process, only answers and innovative solutions. How to recall the question later?
Looking through the textbooks, notes and counseling books used by senior one, I asked my classmates, that's how I came over at that time. The counseling book took three years of college entrance examination, two years of simulation, and summarized the teaching materials according to the outline. There are also examples in the textbook. If you can't find it, ask the teacher. The first round is to consolidate memory and review carefully. The teacher will talk about it. Just don't understand or can't solve it. Don't be afraid to ask the teacher.
