1. I wonder what your regional requirements are? Personally, I feel that the schools in Beijing are better, and the test sites, Jiaotong University and the capital economy and trade are all better. You can repeat as long as you cross the line. If you want to choose in Jiangsu, Agricultural University and Normal University are better test sites, but there are other local schools to choose from.
2. If math is really not good, I suggest you take the administrative exam instead of math, and pay more attention to other subjects, and the probability of success is also high.
Generally, mathematics is a national unified examination, and there is no difference, unless other schools can make their own propositions, such as East China University of Science and Technology in Shanghai? (It seems that I can't remember clearly) It must be easier than the whole country.
It's a good thing that you started preparing so early. Make sure you didn't take the math exam first. If you do, don't worry about anything Just concentrate on math. If you don't understand repeatedly, ask the teacher. Remember that if you don't ask the teacher, it will only prove that you are a bookworm and unworthy of studying. Hehe, I hope what I said will help you a little.
