I was just throwing some numbers around, but now I am looking at my schedule. We are technically in the midst of 32 credits. However, 15 of those credits are full year courses. Those courses include DA and Operative lecture at 3.5 credits; Operative lab at 6 credits; DA lab at 3 credits; and intro to clinical dentistry at 2.5 credits. The courses that will conclude at the end of the semester are Histology @ 5 credits, Physiology @ 6 credits, Correlated sciences @ 1 credit, Radiology @ 2 credits, and Gross Anatomy @ 3 credits. Gross anatomy was in the summer semester (our only class) and we spent 20 hours a week (4 per day including Lab +Lecture). So besides Gross Anatomy and ICD which we spend 4 hrs a week in, you are correct, the credits matchup. My point was that Radiology, ICD, Correlated Sciences and DA / Operative lecture are all pretty cake classes. Not all credit hours kick your *****. However, Histology, Physiology, Gross, and Labs are quite time consuming and worthy of the credit hours.
In undergrad, I had to put pretty even effort into all my courses. In school so far, most my effort goes into Operative Lab, Physiology, and Histology. And this makes sense since those 3 courses make up 17 credits
