University is what you make of it. From my own personal experience, so far, of Warwick I can say that this is deffinately the case.
You will, of course, always find people who want to get a 1st in their first year; however, with most courses only requiring a 40% to pass the year, with no precentage going to your overall degree, many do not take it that seriously.
Roote's reputation is largely exaggerated, or at the very least did't hold up this year. I'm at Westwood (Hampton), and without a doubt we have developed the largest reputation for being the more 'sociable' of the accomodations (roadtrips, pre-drinks, parties, naked forfeits and, of course, the most fines in Warwick history!).
There is a new union being built, which will be ready next term, and with nights out to Cov (mainly Kasbah and Lava-Ignite) and Lemington (Evolve) we've certainly made do. Add in the odd night to Birmingham and the sponsered events, and your week gets full quickly. The Uni-Express do deals, leaving from the union and Varsity, to Coventry, Lem and Birmingham which include transport, entrance (with queue jump) and then a free drink.
Along with 'going out' there are many society events held throughout the year. This all depends on your attitude and what you want to get from university and how outgoing you actually are. Those who speak lowly of Warwick's sociability are truely uninformed individuals.
EDIT: Watch out in freshers week- we're deffinately going to snag some fresher's T-Shirts and crash your exclusive events. Hilarity will ensue. You were warned.
