I'm a COMSC student at Cardiff Uni, in my 3rd year at the mo. Is there anything specific you want to know?
1st year is bliss, just a big
up really
2nd year is more of the same but with harder exams
3rd year is literally living hell, i cant remember the last time i had a social life
The school itself is okay i suppose, bit unorganised at times though. Cardiff is a great town for students, cheap and everything is centralised.
