I'm a sophomore! This is my one-year experience in high school! My math is not good either, it can be said that it is extremely poor! But now I understand a truth, that is: if you want to pass the exam, you must take notes; If you want to do it well, you have to do all the questions in the book well; It's a little troublesome to be excellent. It is necessary to thoroughly understand the notes, homework and questions in the textbook and expand them appropriately, that is, to buy a good teaching reference, such as winning the championship easily or fully understanding the textbook! Flipping through magazines when you're free will definitely work! Try it if you don't believe me! Life is only accidental and impossible! I wish you success.
