How hard is A level maths?Watch
What I would say though, is that I wouldn't take it because "everyone is doing it", or because " it's the most popular", take it because you want to. What's best for the majority may not always be best for you. Have a sit down and brainstorm careers you would be interested in and if maths is beneficial, then do it. A "B" at GCSE shows sufficient mathematical ability to be able to do A level maths if you put your mind to it.
I just did a taster session today in class to see what A level maths is like, and it was horrible, i did not get anything!? For GCSE im 100% certain i got a B but quite it wasnt a high B rougly 98-108 ums or so. I want to do maths because everyone is doing it and it is the most popular , and it also leads to many other careers but i just dont know if i should do it? just 1 hour of A level maths overview and i was lost..
If you want to perform well in maths related subjects such as A-level chemistry and especially physics you'll be fine if you did well in GCSE level maths, not that all aspects require the application of maths, however if you are going on to chemistry and more particularly engineering/physics/computer science degrees maths at A-level is essential.
Actually even though you don't use much A-level maths in other A-level subjects, you are at an advantage in nearly all worthwhile degree courses with a maths A-level
The applied module for AS is the trickiest bit in my opinion. Mechanics and decision is basically entirely new to you. Even S1 is a different style to GCSE, and I feel like you really need to understand what's going on as with applied modules they can really vary the questions. In core maths, it's just a case of knowing it, understanding it, then solving every problem and learning through that, the more problems you do, the better you'll get in those.
A2 maths is obviously more difficult than AS, but it isn't insane. I've done C3 and C4 too, and there are some confusing topics. C4 integration can be quite challenging at first, and can throw you off, and make you feel like you're doing something genuinely hard, but again with practice from day 1 you can do well.
If you like maths, do A-level maths!
