Personally, I suggest you use the bibliography Advanced Mathematics in the syllabus, but if you already have calculus, you don't need to buy it, because the main contents of calculus are all in calculus, which is completely enough, but you can buy another copy of Advanced Mathematics if you have the conditions.
In addition, I suggest you read Book Review by Li Yongle and Wang Shian and 36 Lectures by Zhang Yu. Mathematics for postgraduate entrance examination is a subject with extra points. Study hard and come on! I wish you an ideal university.
