yeah, they did their best to spread out exams for us this year, but the system is far from perfect right now. actually, we had a survey conducted in class earlier this week so we could give our feedback to the faculty. definitely expect a similar set-up next year with just a few minor changes.
i'm not exactly sure how systems-based and integrated curriculum are defined, but here is my explanation of the curriculum: all the courses (biechem, physio, anatomy, embryo, etc.) are coordinated so that the material is presented in the most efficient manner (i.e. no overlap amongst classes, which was apparently a big problem previously) and that everything is "integrated." for example, a couple weeks ago we were studying the physiology, anatomy, and histology of the kidney, and right now we are focusing on the physiology, biochemistry, and histology on the endocrine system.
regarding the lecture/PBL distribution, we seem to get about 1.5 weeks of hard science on a given system and then have a few days of "clinical correlation" and "case conference" lectures - we had a handful of biochem and MCB sessions earlier in the year that were closer to PBL, but those have basically stopped. then, for physio, there are "facilitator sessions" about once a week, which basically consist of an M1A (who have previously taken and done well in medical physiology) going over old exam problems with a group of about 20 other students. of course, we also have a lab of some kind (anatomy, clinical reasoning, histology) once or twice a week.
