personally I think knowledge in physics and maths is needed cuz that's very much used in all aspects of engineering. It's not impossible to do but you definitely need to put your head in maths and physics books to get on the level that you need to be on. If you don't like maths or you're not good at it, then it will be difficult I must say. I'm assuming you only done maths up to GCSE level which is very basic compared to A level maths. The guy above is right in saying that they start off with the relevant A level maths stuff but then they expand it to harder maths later. A level maths is then the 'basics' which they build on so you definitely need to learn it quickly.
From personal experience, I've seen mates who didn't do maths in A levels (although they did engineering in college without much maths) and they struggled with it, most of them had to retake the maths exam and some changed course (similar course - more to do with management in engineering - which doesn't have the maths module in year 2) to avoid doing the maths.
Long story short, your abilities in maths need to strong otherwise you'll find it difficult. For physics, you can get away with learning the theory most the time but again, it requires maths to solve the problems, especially in mechanics problems.
