I'd like to chime in on this. Like army said, classes start off kinda doing their own thing for the first couple weeks while you get the basics of the basics out of the way. However, once things get rolling (3 weeks in), it moves to a sort of systems based approach. So, to the best of their ability, course directors for developmental bio, histo, and gross have you looking at systems from their respective vantage points as well as ICM has you examining SPs in those systems. i.e. you'll dissect the eye and ear in gross lab, while you're learning about the development of them, while you're learning about the histological features, while you're learning how to do HEENT exams.
I know army noted on this, I just wanted to reiterate that it's as "systems based" as they can make it, without fully committing to a "systems based" curriculum. I'm very happy with it. One of my buddy's from undergrad is at a school where it is strictly systems based, and after looking at his schedule and such, it makes me appreciate UTH that much more. Just my personal preference.
