Judging from your current grades, your grades are not ideal. In order to get into high school, you must study hard in all subjects, starting with the basics of each subject. If you speak English, you should recite the words first and understand the grammar. For mathematics, you should list the knowledge you can't know, ask your teachers and classmates, and review it in time if you understand the knowledge! Make use of the time before the middle school entrance examination, study hard, review with the teacher and improve your grades.
