The new curriculum (we're the second class to participate) is very integrative. They make a big effort to cover all sides of a body system from multiple disciplines. For example, during Normal Animal we covered cardio during week 4. We learned basic thoracic anatomy (organs, muscles, bones, vessels, nerves), basic cardio phys, and thoracic radiology all in that week. It's very helpful to have anatomy talk about the heart, then see how it works in phys, then see it on radiographs all in the same week (and on the same exam).
Speaking of exams, you'll have one exam every two weeks on Mondays that cover all lecture material from the last 2 weeks. Then a cumulative final exam, mid and final lab exams, and group assignments sprinkled throughout.
Normal Animal is basic anatomy, physiology, radiology, cardiology, pharmacology, nutrition, etc. and you’ll do a lot of hands on stuff with animals for labs. Basically no diseases, all normal. It's a nice and easy intro to vet school.
DWT is all disease. Bacteria, parasites, viruses, clinical pathology (blood work), anatomic path, etc. Lots of time looking through a microscope in lab. The integrative theme kind of breaks down for this class, because you can't really integrate bacteria with parasites and make them overlap nicely. This class is definitely more difficult than Normal Animal, but is really not that bad if you keep up with studying. The current second years freaked us all out about this class, but they made some significant layout changes for us and it went pretty smoothly.
Moving and Sensing is musculoskeletal, eyes and ears, derm, neuro. This one deals with normal and then deals with disease (as opposed to separate classes for normal and disease like first semester). We're 5 weeks in and all our labs have been anatomy of muscles, vessels, and nerves. So far this class is less integrative than Normal Animal but way more so than Dealing with Threats. We're only 2 exams in, so can't speak much on total difficulty yet.
You didn't mention Becoming a Professional, but it's basically anything non-science related in the curriculum. Client communication, finances, grades for walking the teaching dogs, etc.
