▼ New semester study plan
The new semester has started, and I have learned a lot. Seeing that all the students have plans for the new semester, I will start planning for the new semester, so I drew up a timetable.
First, because my math is not ideal, I will study hard in math, do more exercises and read more extracurricular books about math in order to improve in the new semester.
Secondly, we should develop the habit of previewing the text in advance, preview the text to be learned on the same day in advance, and review more, especially in the morning and evening, because the memory is better in the morning and evening.
Thirdly, taking more reading notes and abstracting good words and sentences are helpful to the exam and my writing.
Fourth, play less computer and watch less TV, because it is harmful to your eyes and affects your study.
This is my study plan. Actually, there are many more. Because I can't remember it at the moment, I have to start with these points. At home, I hope my mother can supervise me. At school, I want to invite teachers and classmates to help me. Let me improve in all aspects of the new semester.
