Chinese: review the new words first, then let parents dictate and write the wrong words several times; Read the important and difficult sentences in each lesson several times, and look at the notes next to them; It is also required to read more and recite more (including comments), because this is also the key and difficult point.
Mathematics: reading and reciting formulas; Turn out the wrong questions in the exercise and do them again to deepen your impression. There is so much math that there is no need to review it.
English: remember difficult words, memorize them skillfully (for example, actresses can think of S as a girl's curly hair), and don't memorize them by rote; Read more key sentences and recite the questions after class, because that's what the exam is for. In fact, English is almost the same as Chinese. Work hard.
I wish you progress in your study!
