Prepare one or more file bags (if you are a senior one, at most three are enough). Because there are many junior high school materials test papers, commonly used ones need to be put in schoolbags, and those that are not commonly used need to be sorted at home.
For Chinese, you need to prepare "compulsory extracurricular books for junior high school", such as The Adventures of Thomson. A modern Chinese dictionary, composition guidance and so on.
Mathematics, compasses, trigonometry, as for the calculator, it should not be used and can be ignored. There must be a draft.
In English, we can usually buy a small tape player, because we need to play tapes to exercise our listening. I don't think it is necessary to use an English-Chinese dictionary. Actually, it's better to have a dictionary on your mobile phone.
Geography doesn't need to buy a globe. Buy a map of the world.
Biology, there is nothing to prepare for this. Buy at most a few cards, cell structure charts and the like.
History, first recite the songs of the dynasties.
Politics, what you need is to exercise your memory.
Physical education class, because there is an exam in grade three, you may use volleyball and skipping rope.
I still hope to prepare a rough draft of the above subjects, because some words or place names are difficult to write and remember, and writing them several times will help me remember.
We need to prepare: 2B pencil, black charcoal pen (ordinary black gel pen will do) and 2B eraser (this is easy to use).
In addition to the subjects to be tested, there are also art and music. Art needs to prepare things for drawing, such as sketch paper, watercolor pen, 4B pencil, marker, etc. There should be nothing to prepare music for.
The above is my summary, I hope it will help you! ヾ(@^▽^@)ノ
