Jump from year 2 a level maths to year 1 and jump from year 1 fm to year 2

Hi, currently year 11 going into year 12. I've self studied all of a level maths (got 94% on a pure past paper in less than half the time) and am currently on chapter 9 of core pure 1 further maths. I've heard from people everywhere that the difference between maths and fm is monumental, but I haven't really seen anything ridiculous yet; just a lot of content. Is it going to get harder? Are the modules difficult? Is the difference between year 1 and 2 bigger than in maths relative to their base difficulty? I want to know how much I need ot study to ensure A* in both come July next year

Why are you thinking of taking them early? What is your plan for Year 13?

i'm taking them early to study higher-level maths and spend more time drumming in year 13 (want an ftcl diploma). i'll still have 2 more a levels that year + advanced extension award so it's not like there'll be a shortage of things

What are you planning to study at uni? Most will want to see three A levels taken in Year 13 ...

mathematics with physics at cambridge. i could also take chem in y13 since i will be studying it unseriously but it just as easily can be serious. i just want to finish a level maths and fm so i can start learning higher level maths with a good foundation, drumming is secondary tbh

Cambridge won't like you taking them both in Year 12 - they like to see you can cope with a 'normal' A level load. All my Maths applicants either do all 4 in Year 13 or take Maths in Year 12 and the other 3 [including F Maths] in Year 13. Remember you will have to take STEP as well .. and 50% miss the STEP part.

hence why i stated i can also do chem in y13. i know about step as well. i plan to learn it after i finish further maths
