I'm a fresher at HMC reading Theology. (Technically I'm a second-year, since I'm Senior Status, and am the only second-year theologian at the College.) I'm 25, and got my first degree 3 years ago in Theatre and Psychology at NYU. I then entered a Psy.D. program in Clinical Psych, which I left half-way through my first year, and have been working as a professional actor and office admin for a grassroots theatre non-profit since then.
As Eve said, most of the students are in their 20s, including quite a few at the younger end of the spectrum. (I'm actually older than most of the students accepted last year.) While we have one of the higher percentages of international students, there are also many English students, so it is in fact a good mix, not dominated by either internationals or domestics. (And of the internationals we have are people from the U.S. to India and regions in between, mainly Europe.) The JCR is always a comfortable and friendly place to hang out (especially if you play pool - we have one of the only free JCR pool tables in Oxford), and people hit the pubs regularly. I live out, so I don't participate in as many of the social activities as others do (partly because I also have made many friends through the Catholic Chaplaincy, where I can probably be found if I'm not in College, and so I split my activities between College friends and Chaplaincy friends). But even though I live out I've still made many good friends in College, and feel just as welcome at bops and things as if I were living in. (I also attend Hall as often as I can - excellent food and conversation! - though the Formal Halls twice a week clock in at over an hour and can really eat into essay time if you're on a deadline.)
Our college has a reputation for being the friendliest college, and it really is true. The staff, faculty, and students are all quite welcoming, and I haven't noticed any cliqueishness myself. Even though I didn't apply to HMC, I'm happy I was pooled here. It's a really wonderful environment, and I look forward to welcoming you all next fall. (I also have a friend who's a barman at my local pub who applied to HMC to read English after I showed him around, and he just informed me he's been accepted! Please welcome my buddy Gareth next Michaelmas.:-))
Congrats again, and best wishes for the New Year!
