Q: Is it meaningful to do the simulated test paper for the senior high school entrance examination in the summer vacation? Does poor junior high school mathematics have a great influence on senior high school mathematics? What should I do? Poor math is a serious injury to high school study career. It is necessary to study hard. Mathematics in senior high school is more difficult than that in junior high school. It is not recommended that you do the simulation paper of grade three again. When you are free, find a high school math textbook to preview, so that you won't be so laborious to learn. In addition, if you think it is too difficult, I suggest that you choose liberal arts mathematics to be simpler than science. I hope my suggestion is useful to you!
