I studied in the UK. And honestly it was very different. There was no one textbook..they gave you a list of like 10 and told you to choose one. My biggest problem is that my entire grade for 3/4 classes was based purely on 1 or 2 2000 word essays because, as you pointed out, the exams are at the end of the year and since I was there only for the term I couldnt take the exams. The thing about the essays is that to get a first (their version of an A) your work is supposed to pretty much be good enough to get published. Frankly I just didn't have enough experience with science writing. One of my essays was for a Functional Neuroanatomy class on the evolution of the olfactory system and another was on "The effect of benzodiazepines on nerve cell function". Big change from what I am used to!
That being said...my profs said nobody ever gets over an 80%, but an 80% there is a first, so now its up to my institution to translate the horrible percentages by our standards in to what I can only hope are good grades.
Oh, and btw...I wasn't as focused as I could have been- I got married just a few months before I left and it was harder than I expected! But still worth it =)
