Conversation Between llacerta and Insan-e

Hello there!
I just wanted to ask you some questions, I'm new here and I'm not sure whether I'm doing the right thing..posting questions on your "wall" and such. So forgive me. :P
Anyway, I simply wanted to ask about psychology in Royal Holloway..I chose it as my insurance and UCL (Psychology and Language Sciences, a new course..) as my firm.
It's exam month and I'm starting to doubt my ability to get 3 A's, although I'm doing 4 A levels.
I personally predict at least 2 B's and 2 A's.. if not 1 C, 1 B and 2 A's. I'm pretty sure UCL would reject that, but would I stand a chance with Royal Holloway?
And since I chose it as insurance, I might not be able to apply for accommodation, but I applied for accommodation in the International Hall (as I am an international student) in central London. Would it be possible for me to take the train every morning and evening to and from Egham? It's not an issue of cost, but will the schedule enable me to do so, or will it be EXTREMELY difficult (I don't mind if it's "uneasy" though)?
LAST question (sorry for long post), I'm aiming for studying Educational Psychology in postgrad, is the course in Royal Holloway a good choice then?
Okay I think I'm done... THANK YOU!
