Continue to maintain their dominant disciplines and don't let them back down! ! Then talk more about science, especially math! Since math is not good, master the basic knowledge first, and then change the basic questions! Every exam is still based on the basics, so the basics are very important. If you can answer the basic questions correctly, I believe you can answer about 70 questions correctly. Also, if you don't understand, ask the teacher and ask your classmates. Do more basic questions! !
