How tough is doing entire maths a level and exam in year 12?

no no, there's no disadvantage at all!! in fact two of my friends in my class both got offers at imperial

Thanks for ur help, I also think that becasue im only doing three a levels i should find it slightly easier anyway thanks

Because I’m doing further maths in year 12 from September, alongside maths and physics, I have to do the entire maths a level in year 12 and the exam and the end of year 12. We then Start further in year 13. How tough is this? As i want to go imperial and they require an A star in maths

Right so after discussing over email with the hierarchy of my school today, I have now been aware that when you do the maths A level at the end of year 12, if you do not get an A or A star, then you must drop further maths(which you start in year 13) and retake maths in year 13. As I had originally picked Maths, Physics and Further Maths (only three a levels), if I was unable to get an A or above, I would be in danger of only doing 2 A Levels in year 13, as further would have been dropped. So, they have insisted I do 4 A levels, so I would still have to study three A levels in year 13, not 2. So I have decided to pick Maths, Physics, Further and Product Design. The problem is that I want to go Imperial for artificial intelligence, who require an a star in normal maths, and prefer further maths over product design. For me to attend that uni, I would have to work really hard and try to achieve an a star in maths in one year, or at least getting an A, meaning that if I had to drop further maths, I would find it difficult to get an AI degree at Uni (as further maths is very essential to this). I know that this is very complex, however I will be discussing more over the phone with my head of maths, to discuss these scenarios. Getting an A or A star (preferred) is a lot of hard work to achieve in one year and I am willing to take that hard work and dedication.

My college had the same system, and I got an A* in Maths at the end of year 12. I really liked doing it this way, because it felt like I improved so quickly! My other subjects were Chemistry and Computer Science, and I personally found both of these quite easy at AS which gave me more time to spend on Maths. I dropped my 4th subject at the end of year 12, so in year 13 I just had Chemistry and Further Maths.
I got an 8 in GCSE Maths, and hadn’t done further/additional maths before, but I still found it manageable. I had mostly caught up to the others by the time we finished the AS content.
