What maths exactly? That directly to do with PPL study? It's not in the slightest bit difficult, to be honest. Speed Time Distance calculations and half decent mental gymnastics for some arithmetic is all you'll need.
The maths involved with the degree study, especially when it's an Eng, will be considerable. If you have A-level maths then you shouldn't find it difficult, if you don't I expect you will need to do a compulsory foundation module in year 1, if they allow you to start without it at all.
