These things vary from teacher to teacher, depending on whether the teacher's lecture is detailed, whether it is expanded, and what the requirements are for handing in the wrong questions regularly.

If you arrange it according to your own, the general mathematics you learn well will take about 50 pages, which is equivalent to the front and back of a 32-format book. This is a semester. Of course, the math paper is gradually increasing, and you will get it slowly.

Physics, the first semester of senior one is less, which is the deepening of some knowledge in junior high school, about 2 or 30 pages. I will also get 50 pages next semester and senior two.

In fact, chemistry is the easiest to cope with the college entrance examination in science, but there are a lot of calculations at the beginning of senior one. If the foundation is not solid before, at least 560 pages should be prepared. If it's better, thirty or forty pages will be enough.

These are all estimates. I usually used lesson preparation books at that time, which I modified. I hope it helps you.
