Language: memorize all the notes of classical Chinese and ancient poems. Don't be afraid of hard work. Modern Chinese reading is good at two parts-narrative and expository, and the composition is accumulated by peacetime.
English: Listen to more English tapes, watch more original English discs and learn to read aloud. When you read more, you will naturally master some grammar, and you will feel comfortable seeing those who choose to fill in the blanks (provided that your spoken English is good). If not, it's good to specialize in grammar and introduce you to a book. Write composition every day. Don't be greedy. The important thing is to persevere.
Chemistry: recite all chemical formulas, periodic table of elements, chemical valence, be sure to recite ~ ~ ~
If a teacher does an experiment in class, he must watch it carefully and try it himself. This is very important. This is the experience of being a person who has been there before.
Physics: sort out all concepts according to optics, mechanics and electricity. Clear your mind.
Mathematics: Do more problems, solve a problem in several different ways, and broaden your mind.
Politics: Watch the factual news every day, such as news broadcast, both at home and abroad.
History: There is only one word-back.
These are all my personal experiences. If I can do it, I will definitely get the ideal grades ~ ~ Remember, no matter which course I don't understand, I have to ask ~ ~ ~
Students, come on!
