Borrow a book from the ninth grade first. It must be the whole grade. Chinese has a simple hobby of reading after class and taking the mid-term exam this year, so we should read the books after class carefully, and there will be no time in grade three! ! Mathematics should be previewed, and physics should take time to read the previous books while previewing, so that it will be more labor-saving in the general review in the second half of grade three. Chemistry should memorize the periodic table of elements and write it silently, so that it can be easily learned when learning chemical equations. Buy some books that explain, don't have too much practice, but have detailed explanations, so that you can understand them. Basically, we can't play much time this summer vacation and the next winter vacation, because everyone is studying! ! So come on! !
