This question first depends on what school you are applying for! For different schools, the difficulty of mathematics is different! You can't just say which is more difficult than which! If you apply for 985 and 2 1 1 in 37 universities across the country! Part of the math problem is to solve it independently! To tell the truth, it is generally easier to write questions independently than to take the unified exam! Here are two more aspects! 1. Generally, self-made questions have designated teaching materials, which can be reviewed according to pertinence! 2. The professional investigation of independent questions is relatively strong, and the questions of the past years are of course the best collection you choose! There are areas here, too! Because now the postgraduate entrance examination is scored! But it's relatively difficult to do those urban math questions that make us feel developed! There are also differences when marking papers! (You will know later) If you are not admitted to these schools! The exam is a national unified exam! Then there is no qualitative difference between 304 and 303! Besides, you didn't report 37, so it's in it! You are a science major, so you usually count as one in the unified examination! Liberal arts is different! You'd better ask the previous seniors, they can give you good advice! I hope you can succeed! I hope I can help you!
