The high number specially inserted in Guangdong is the same test paper in the whole province, and there is no high number of 1234 (that is only for postgraduate entrance examination), which means that no matter what kind of science and engineering major you take, as long as you take the high number, the questions are the same.

As for the teaching materials, I recommend Advanced Mathematics (Volume I and Volume II), the fifth edition of Tongji University, and Advanced Mathematics and Calculus edited by Zhang Deshun. I am a candidate in 2009. When I review, I mainly read the textbook edited by Zhang Deshun (because that book is the textbook of our university), because this textbook has been able to contain more than 90% of the contents of the examination syllabus, and then combined with the two advanced mathematics of Tongji University to strengthen and consolidate, mainly to do examples and calculations in Tongji Advanced Mathematics, and to see those knowledge points that Zhang Deshun did not elaborate in the textbook. In fact, if you do more, you will find that some exercises in these two sets of textbooks are the same.

The contents of two advanced mathematics books of Tongji University are relatively comprehensive (but few chapters are required when inserting), but the difficulty is slightly higher. Zhang Deshun's textbooks are almost specially prepared for the special edition exam. If your math level is good, you can review it directly with Tongji textbooks. If the foundation is not very good, you can refer to my review method. As for calculus, I haven't even read the book, hehe. The high score of 86 points in 2009 has met my own requirements.

I hope I can help you. Please continue to add if you have any questions.
