Self-Studying All A Level Maths and Further Maths as an International Student

I'm not enrolled in the UK education system, but I'm planning on applying to a university here, but I'm aware that my nation's maths content isn't necessarily the same as A Level maths and further. Thus, to make sure I have covered all of the same content as UK applicants, I'm planning on studying all of A Level maths and further (I still have several years before the applications process, which is plenty of time) in my spare time, in addition to all of the other maths qualifications for my own region. Personally, I'm more of a textbook learner (though I certainly don't dislike watching YT videos on the side, as an addition), but there appears to be a huge variety of different A Level Maths and further textbooks, so much so that I'm having a hard time figuring out which ones to choose to read. Could anyone give me any advice. I appreciate it SIGNIFICANTLY.
