Subjects for 6th form

I am currently in year 11 and for my college subjects I have chosen Maths Chemistry and Physics. Could anyone tell me if that is good for an engineering degree in uni or if I there is something better?

Further Maths might be good to take as a 4th A-level. But, this depends on the university.

Thank you but isnt that too much of a workload? Also what is the difference between Maths and Further MAths?

Most people only recommend taking a fourth A-level if you are studying both Maths and Further Maths (FM).
Although I don’t take either Maths or FM myself, I’ve heard that FM essentially builds on the topics covered in A-level Maths. While it’s more complex, it can be more manageable than taking four completely different A-levels because of the significant overlap between the two.
Additionally, FM is much closer to the kind of mathematics you'll encounter at university, especially in courses like engineering. It provides a good foundation for mathematical concepts, which would be beneficial for your degree. While it’s not required (you could learn the required maths at university), having FM would give you a head start.
That said, I’d only recommend taking FM if you’re achieving consistently high grades (like an 8 or 9) in GCSE Maths. While it’s possible to manage with a grade 7, you would need to put in the effort to catch up on content.
Physics, Maths and Chemistry is still a great combo, and most universities would be completely fine with it. But, if you are interested in Oxbridge or imperial, than FM is definitely something to consider, since stats show most students take it for engineering degrees, and very few without it get in.
Hope this helps!
