Mr c152 man,
I'm a graduate of the great place they call CCAT. You can basically work as hard as you like - it's up to you at the end of the day! What I will say though is that it will reflect in your final results. Had a few guys there who only seemed to be present because mum and dad thought it would be a good career for them. They didn't work hard and are probably still there now (2+ years on). And us that did actually want to work hard are flying for airlines.
Cranfield itself, now then. Spend as little time in the place as possible! Place will drive you mad if you don't get away from it (especially in the dark and lonely groundschool nights). Have fun, the place has done many (including me) proud. And Paul Hardie is great (despite what the other thread says - those were the lazy gits who he didn't like).
