Psychle, I was in a similar situation to you!
I'm in my 4th year of my Mechanical Engineering degree having started it at the age of 32. I did a uni Access Course in maths and physics two evenings a week before commencing the full time course to brush up on the fundamentals as it had been 15 years since I'd done any at school.
I think I may have struggled going straight into the course without doing the Access, as mentioned above many subjects in 1st year are pretty maths intensive, but with this preparation I found 1st and 2nd years to be pretty straight forward.
