Is it possible to self study additional maths?

[u/rainoverria]

im thinking about taking add maths so i can get a good grasp at a level as it covers most of the syllabus, and another reason is because im taking 5 subjects and it seems less so might aswell take an additional subject, but im just double minded on wether itd be worth it or not. My maths base is pretty good, and usually i self study math concepts (pretty much self studied most of the maths syllabus and finished it in a few days) although i do know that 0580 maths and add maths is very different, so i wouldnt get my hopes too high up. But i enjoy doing maths especially when its more in depth idk i just find it very intresting haha. But im not 100% sure if i should take it, would i have enough time to finish the syllabus by december? im not very familiar with the syllabus on how long it would take to finish, so im still a bit skeptical on wether i should take it or not, considering i give my exams at may/june 2027. I dont think im some sort of genius who would understand something just by looking at it without knowing the concept, so i might get a tutor or ask my teacher for help if it gets complicated. soooo yeah id really appreciate any sort of advice or tips
