No problem!
Yes, most of the small group teaching is taken by lecturers and/or doctors. We do a few PBL cases every term. Although not as much as PBL medical schools where it is the main method of teaching. In 3rd year, there are some 'proper' PBL sessions to get ready for going to clinical schools. St Andrews has a more traditional systematic teaching than PBL unis. Personally, I believe that the firm foundation of medical knowledge you get at a place like St Andrews is invaluable. Some people prefer PBL unis, but you would have to be incredibly motivated to learn as much as you would at a more traditional uni like St A. Dissection is 2 hrs a week - that's taken either by retired surgeons, or younger doctors (who are hoping to become surgeons), and a few anatomists. We do quite a lot of group work. It doesn't go towards your grade (that's exam dependent). We put together a few presentations a term in our groups of 8.
The patient contact in St Andrews has changed recently. Now there are no attachments in 1st yr. All your clinical and communications skills are practiced on locals who are paid to have you prod and poke them (which is great when you're a nervous little 1st yr!). In 2nd year, you have one day of GP attachment per fortnight in Fife or Dundee, or an attachment with Cameron Hospital, St Andrews community hospital etc. In 3rd year, you have fortnightly attachments at hospitals around fife. The med school is great - you just turn up at the med school and get taken by taxi or coach to your attachment free of charge. Personally, I don't see the advantage of lots of early clinical exposure. I had GP attachments in 1st yr and felt it was a bit of a waste of time as i didn't know anything and couldn't join in/practice clinical skills. There's plenty of time for seeing patients in clinical years! At St Andrews, we actually learn more clinical skills than people at very 'patient orientated' med schools, which is quite surprising. Consequently, when you leave st andrews, you are able to examine every major organ system and a lot besides which gives you a great start to clinicals.
I know it says most internationals go to manchester, but in my experience, people go where they want to! Edinburgh has places set aside for internationals. Lots of my international friends are going to scottish clinical schools. I'll try to find out exact numbers for you.
