Which math books to choose?

Question

Books

Good evening everyone. I am a student of the 1st year of physics and technology and they began to teach us at the university Mathematical analysis. My knowledge, understanding (and grades) in school mathematics in the last grades were not so good - by 6-7 on a ten-point basis. Things are also not very good in math-analysis classes. Therefore, I want to ask you what books you can advise me from the following (and not only) to understand most of the material:

Theory:
Kudryavtsev L.D. Course of mathematical analysis, 2.3 hours
Zorich V.A. Mathematical analysis (2nd part)
Fikhtengolts G. N. - course of differential and integral calculus (part 2,3)
Gorbuzov V.N. Mathematical analysis, field theory

Collection of problems:

Demidovich B.P.. Collection of problems and exercises in mathematical analysis
Kudryavtsev L.D. and other Collection of tasks on mathematical analysis. Functions of several variables
Collection of individual tasks of the general edition of Professor Ryabushkov
Reference book on higher mathematics, Volume 1, Mathematical analysis, Lyashko I.I., Boyarchuk A.K., Gai Ya.G., Golovach G.P.

Thanks in advance.
