I had some of the best times of my life at uni but also the worst. I loved the place, my rooms, my college, the supervision system and tutors, my friends and all the traditions that went with Cambridge life, but the course was so so difficult that it made me hate almost everything about it. I think it was a trade off- if I went to a university where the course was easier I might have been happier, but then I would have missed out on all the good things and the support systems etc, which suited me to a T. Plus some of the bad stuff (e.g. my friend dying) could have happened anywhere so who knows....
