Overall the curriculum is great! PBL is the best for both studying at your own pace and starting board studying from day one (constantly using board review sources to master material for PBL exams). After Anatomy (ends in mid-october), your schedule really opens up. Exams once pbl starts are usually 3 exams a semester (these are huge exams; 200 questions, 4 hrs). In a way its like taking a mini board exam, which can be helpful. While i've yet to take boards, i certainly feel like im being prepared for them. PBL is what you make it. If you're not putting in the effort it's going to show. Professors are extremely open to helping and there are also tutors available ready to help out for those struggling or looking for clarification. Hope this helps.
