When reviewing, as far as the content is concerned, try to choose the content closely related to the text for review. This can not only complete the task of reviewing the text, but also help you form the ability of migration. In addition, the content of each review should not be too much, and the amount should be appropriate. Attention should be paid to the interlacing of Chinese, mathematics and other disciplines. Try not to concentrate on a subject for a long time, otherwise it will easily lead to fatigue and the review effect is not ideal.
