1. There is no difference between Paper A and Paper B, just the question numbers are different, just to prevent people from cheating. 2. It is easier than the college entrance examination papers in some places! It is usually taken by art and sports students, and it is not very difficult.

It is a national unified examination, but the current level of the exam is not very important, I suggest you just treat it as practice.

You can find some real simulation test questions to do, and there should be questions from previous years on the Internet!
