Hi,
Thanks for the questions. Firstly, all undergraduate colleges offer the archaeology course. When choosing your college you should consider its location, size, sporting/music facilities etc. Each college is different, so you can really make it a personal decision based on the kinds of things you're interested in.
Regarding the admissions assessment: students will have to sit a one-hour written test on the day of their interview which will involve reading a short passage and answering questions on it. You can't really revise, as we don't test for knowledge, but good read some books on archaeology and find out what's currently happening. You could also visit some sites and think about how material world affects people. Also, showing enthusiasm and passion for the subject is important.The test is just one element of a wider portfolio of information we are interested in.
I hope that helps answer your questions!
Best,
Sue
