I’m a private candidate , I’m taking full A levels(I haven’t taken AS levels) in maths and further maths ,I’m following Edexcel board, now what I’m struggling with is that idk the modules I should start studying like does taking a full A level in a subject means that i got to study both AS modules and A2 modules as separate content like finishing the AS books and then then A2 books or there are books that contains full A level content or what?

I’m Ayaat , I aim to apply for top universities in UK specifically Oxford for a mathematics major, my country’s diploma isn’t accepted in the UK so taking A levels in Maths , FM and physics is the solution, I haven’t started any studying yet, MY biggest struggle is that I don’t know which modules should I take and how many of them, A levels system is totally new to me, I Know that the main aim of this group is to help those who have already started and know how everything works but I’d appreciate it if anyone helps , i have made my researches already but I was totally distracted with different info, I Guess all I need: 1. acknowledge how everything works from the first place 2. the resources I should rely on I’m quite used to self studying so I only need someone to explain the root of everything and the basic theories when needed not constantly , someone i can ask when something is not quite working with me when studying also I need to get all of this done in 8 months time, is that applicable? also I’m good with math so I’ll have the desire to put much effort than the normal with love just to get accepted this is my dream and I only have ONE CHANCE to get there , straight A*s is a must. I’ve finished my first engineering year here in egypt, I’m taking a gap year to get this done and again I can only try for once and no other.
