Well, time is a little tight. I took part in a math contest. It's all about writing. 1 month is really not enough. If there is a preliminary contest, you can find some original competition papers. Look at the question type. Summarize the types and practice the questions. Physics and mathematics are also universal, and they all rely on accumulation. And use some tips to solve problems, the current counseling books are rather confusing. You ask your tutor. Look at what kinds of books were used in previous competitions and find a book with a detailed and clear structure. 1 month, it is better to write more questions. There is really no other way. Crashing is really not the way to compete, just like a math contest in high school. Curve integrals, partial derivatives and double multiple integrals in universities are all involved. So is physics. . . I wish you success! Work hard ~ ~
