Congratulations on following your dream and on getting into University.
I start University in a few weeks myself to study Electrical and Electronic Engineering, at the ripe old age of 36, but mentally I'm still a teenager so I'm sure I'll fit in ok with the lads lol. I'm a single parent so the last few years I've been working part-time and concentrating most of my time on my son whilst doing the odd part-time OU courses to keep my brain active, but it was always my hope and dream to go back to study full-time at University, I only managed 6 months the first time out of school as I didn't like the course I was doing. Now that my son is 14 and my dad has retired, and can help out, it feels the right time to attempt this and to work towards a better job and career. Plus if I wait any longer he'll be going at the same time and as much as he thinks that's a great idea now he won't when he's 18 lmao.
Best of luck with the course, I'm sure you'll love it.
