Hi , my son is at Trevelyan (Trevs), which is known as the friendly college. It is catered, gowned, and holds formal dinners every 3 weeks (optional). Some colleges have a lot more formal dinners (bailey colleges). Trevs is really handily located close to the maths dept for tutorials, and the lecture theatres in the TLC and on the science site for lectures (they are based more in the maths dept in subsequent years, when they specialise more and don't have so many in lectures, so can use their smaller lecture theatres). At Trevs I think 2 landings (12 people ) share a kitchen. The ones in my sons block have been refurbished, and they are like a proper little kitchen, with cooker and hob, kettle, toaster and microwave, decent amount of work surfaces. They don't have ensuites though, and share 1 bathroom between 6, but my son said he has never had to wait for the shower. At least with shared bathrooms they are cleaned for you, and they supply the loo roll! My son also shares a room...don't rule it out, it has been brilliant for him, a ready made buddy, someone to go to meals with, and events with... he has never complained of being lonely or being homesick. He was dead against sharing before the offer holders day, but the students showing him round were singing the praises of sharing, and he was won round to the idea! All the rooms are under one roof as well (unlike other catered colleges), so he can go down to meals in his slippers if he wants... no going outside to get to the dining room! He just loves the friendliness of the college, on the first week they had loads of activities such as a compulsary formal dinner and landing meetings, so you met other people, and werent left to just find your own way. All the colleges have their own sports teams, but collingwood is known as the sporty college, however I have a cousin who went there and he found it a bit full on, a bit 'lads lads lads'. Hatfield also has a strong 'rugby boys' reputation. You can see various college guides and videos on youtube to help you choose, and each jcr (junior common room), has its own facebook and instagram pages, so you can get an idea of what is going on in each college, if you can manage to attend an offer holders day, it is really helpful to visit 3 or 4 colleges, so you can get a good feel for them. We looked around Marys' Greys and Trevs, and he would have been happy with any of them.
