Did you go to open/offer days? - Whats your gut feeling?
Do you prefer city or outside?
If one uni more expensive than another?
Do you prefer bigger or smaller unis?
Do you need the unis to have any accrediations?
Have you considered travel costs, rent costs?
Do you need somewhere its easy to get a job?
Does the uni have a grant/bursuary if you need financial support?
RVC is amazing to get an offer at - Camden campus in London just been this weekend, not cheap and smaller rooms if in halls.
I much prefer RVC and it has a lot of accrediations if you ever wanted to work abroad without retraining.
Seriously I would put RVC at top of list but your decision. Use the above to help make a smaller list.
