I have been there before. I am a 20 1 1 Guangdong college entrance examination student. I used to be bad at math, and passing was a problem! But this year I got 126 in the college entrance examination. Use the formula, provided that you remember the formula! I can't use it, actually it has something to do with the unfamiliar formula. Always recite formulas ~ in addition, not when you meet the same type. In fact, you don't understand this type of practice at all. Ask your classmates or teachers more, and be sure to do it yourself several times. Do more math, think more, and gradually accumulate and improve. Don't try to get there quickly! To tell the truth, if other subjects are good, math is not good, which may be related to your habit of doing problems and your attitude towards math. Otherwise, it's an IQ problem. Sometimes math is very flexible. I hope my answer is helpful to you.
