It's already been said, but I'll add too/elaborate. I'm OMS-I right now. In the early months of the first semester you take Anatomy, Histology, and Embryology. Anatomy has no lecture and you basically read the entire book. Histology and Embryology are both lecture based. During these three classes you don't HAVE TO do any of the recommended readings for PBL. You basically have two weeks of time from the end of Anatomy to cram in your PBL readings ( I don't advise this, but most of us did it so we could focus and do well in Anatomy.) After Anatomy ends, you go full swing into PBL. Your first full block of PBL has 6 cases and you have to choose 80 pages/case then you have to read additional common learning issues that are selected by the faculty. In the second semester it's still 80 pages/case, but it's 7 cases. I'm not sure if this seems like a lot or not, but we choose a lot of readings that overlap. For example, if we need to pick chapters related to the clotting cascade...than we pick pages out of phys, path, pharm, and biochem that all end up saying the same exact thing, so, it's a lot to read, but not all of it is new and really, you end up doing a review bc the material is so repetitive...ends up being a time saver. Also, you can still pick from anatomy, embryo, and histo which will also be review since you've already taken them at that point in the term. As was said, we go through ~1 case/week, unless it's a really easy case. So far, we have always finished the cases 2 weeks before the exam, so we have M/W/F off before the exam and spend that time studying. A lot of people here will finish their first read through of all the material (all 700 pages) maybe 1-2 weeks before the exam and then spend the M/W/F that we get off to review everything. Generally, I set daily reading goals. I pick a day that I want to finish reading by and divide it out and make myself read that number of pages every day. Obviously there are some other classes that you'll be taking at the same time so you won't hit your quota every day, but you can usually make up for it with easy reads or by building a little buffer time into your deadline. I have found nothing to be particularly difficult, but the pace and volume is challenging. It's totally doable though, you just have to stay on track.
