Mathematics is reformed in the second phase. This book is very good, but I don't know if there are any old textbooks.

Physics is the support of the second curriculum reform, which has problems and difficulties.

Chemistry is an old textbook. I can't remember the name of my own book. I'll tell you next time. There is also a set of books that are very good, recommended by gravity! If you add chemistry in the future, you must buy this set of books!
