With the way they have re worked the curriculum, Spring semester is an absolute kick in the teeth. You end up taking anatomy and physiology at the same time, both 5 hour courses. This happens along side of ethics and intro to clinical research, one of which is online, and the other meets once weekly, so while those two are manageable, with anatomy and physiology looming so heavily it makes it incredibly easy to forget an assignment in one of the two easier courses. I took 23 hours in a single semester during undergrad (I was attending a CC and 4 year school, doubling my credits so I could graduate faster) and it wasn't nearly as hard to keep up with as the 15 hours they laid on us this Spring semester.
Scholastically, I'd say physiology is probably the hardest, and I say this even in the presence of 12 years of pretty significant clinical experience (paramedic, flight paramedic, etc.) it is also the only course they end up curving basically every year. This year they only curved it one point, in years past they have curved up to 3 I think (not positive.) this is just another example of how competitive and high stat our class was.
Biostats is not a hard course, but it is a gut check, as it is the first course you take over the summer, it is 4 hours, and you aren't sure what to expect. It is also a "sleeper" because it really can sneak up on you, and before you know it you've got a B, or worse yet a C, and you really don't know how it happened. Dr. Ariel (not sure if he's teaching again this summer or not, but he's a great guy) gives 3 exams with a total of 100 questions for the term. It's really simple, every 10 questions you miss is a letter grade. You can drop from A to B pretty quick, and B to C even quicker. Since it is 4 hours, it can be a nice little hole to dig yourself out of before the Fall even starts.
Pharmacology is the last course we are taking right now, and again, it isn't hard necessarily, but for most of us the dye has been cast so to speak, so it can be hard to find that same motivation we had at the beginning of the program.
So my unofficial list, in order of MOST to LEAST difficult is:
1.) Physiology - difficult in its own right, but with Anatomy and two other classes running along side it, it is definitely a beast. They curve it every year, and that is because it is a killer. (spring semester)
2.) Biostats - not necessarily difficult scholastically, but since it is the first course, it can get away from you in a hurry, and they run MCAT prep, optional biochem, preceptorship, and a few other things along with it. (summer semester, only graded course)
3.) Cell biology - this may be unique to me. I did pretty well in cell biology in undergrad, but this particular course I never quite caught up with. I still did well, but it was more work than I expected. (Fall semester)
4.) Histology - again, this may be unique to me, I don't really love histo, but this class was only 2 hours of credit, and easily took 3-4 hours of hardcore studying for 1 hour of in class lecture time. The general consensus was that this felt like the work of a 4 hour course, yet the contact hours only amounted to 2. (Fall semester.)
5.) Anatomy - everyone on the whole did well in this course and the average for the class was a high B (around 88 I think) but the fact that it was alongside physiology made it hard to manage. This class takes a lot of time outside of lecture. If you have never had a human anatomy course, you are already behind for this class. (Spring semester)
6.) Pharmacology - this course would be higher on my list of difficulty if it wasn't for the fact that this is literally the only time in the entire program where you just have one course you are responsible for. It's the end of the program, 95% of us know what our fate is, and summer is so close we can taste it. Hard to stay focused...you better believe it. Easy to say, "Getting a B isn't the worst thing in the world." Most definitely! (Spring semester)
7.) biochemistry, immunology/microbiology, and the rest of the science credits are about the same level of difficulty. Nothing too hard, just stay on top of it.
8.) all of the non science courses like health disparities, intro to clinical research, epidemiology, ethics, etc. are pretty much GPA boosters. You should get an A in all of these courses without much trouble. They are great courses, and I loved the content, but they were not academically challenging, which is nice once in a while. You show up, learn some cool stuff, make an A and hit the road. If only everything came together that nicely.
So there you have it. That's just my opinion of course, and oharm may move up on the list depending in what my score on the next exam is...I'd be interested to hear other previous MedScis input on this. It can be a very individualized thing as everyone has different things they are good at, but I am pretty sure almost everyone will put physiology close to the top of the list...
