There are still 200 days before the college entrance examination, how to improve science [especially physics] and mathematics quickly. Kneel down 1. I am a middle school student in Nanyang. I took the mid-term exam this time. Personally, I don't think it is very difficult. Do more questions in the college entrance examination over the years. For physics, you can practice multiple-choice questions first. Multiple-choice questions can be divided into knowledge points, and then you can do the last big physical problem of each province and city, and finally break through the experimental problem. If you are obsessed with physics, I suggest giving up the experiment. Leave time for other questions. Chemistry is mainly to practice some big questions and remember some knowledge points. It's no good not practicing science, but it's good to practice more. I suggest doing less simulation questions and more real college entrance examination questions. I wish you success!
