From memory, Freshers goes:
-Saturday - move in and Icebreaker Disco at night,
- Sunday - Comedy Night
- Monday - Massive Monday (the one in Sept 2012 featured Zane Lowe)
- Tuesday - Quiz
- Wednesday - Flirt! (Fancy dress night)
- Thursday - Live music (smaller night)
- Friday - Freshers Ball (Example for Sept 2012)
There just the SU events at night, various other things going on during the day both in the SU and from the Uni itself such as Societies sign up and AU sign up etc
Must does - go to all events during Freshers Week, join as many societies and clubs as possible, make as many new friends as you can, just have fun really!
Lecture sizes vary, for both History and IR, there's about 100-120 that do each subject so the compulsory lectures have about that many in (at the start anyway) and then each module goes from about 40 - 80 depending. Don't have any information on either Law or Criminology, sorry
And yep, there are various parties in the woods, they're pretty infamous, don't think there's been one for a while but there definitely will be some next year!!
Erm, depends! Keele does get slightly dead and boring over weekends but hopefully that will change next year! (Can't say why atm) I would recommend not going home much at all! Socialise with flatmates etc and get to know the area! Not sure about that but I'm in a 4 person flat in Barnes next year and that isn't mixed, don't know about others!
