7c isn't a difficult class in and of itself, but it shares the same bad reputation for unclear test questions that the entire 7 series is known for. I would say that 7c is the most unfair when it comes to test questions. I had a very easy time in 7a and 7b, and though I did end up with an A in this course, it was not without some anxiety. There were multiple unclear/unfair questions on both midterms that resulted in initial scores that were very low. My midterm scores ended up going up about 10% each after many students contacted the TAs and professor about bad questions. To her credit, Professor Das was very accomodating and removed most of the bad questions or allowed multiple answers. Compared to other professors my friends have had, I think that my experience with Dr. Das was actually pretty fortunate. The class is not that difficult if you do the Launchpad readings and make note of what is emphasized during the discussion sections. I found that discussions for this class were much more helpful than those for 7a and 7b, so take advantage of that. I also found it helpful to watch Armando Hasudungan's anatomy and physiology videos on youtube. I would recommend watching once before doing the readings and again to review for exams. My final piece of advice is to remain calm when taking this course and trust the professor. Even though many of us were stressed about our grades during the course, Dr. Das was fair about final grades and it seemed that many of us ended with A's.
