Hey shilayli06, I'm currently in my second year of Biomed at UoM.
The workload is quite intense, especially in the first month of uni where it's a bit of a shock to the system, particularly if you haven't studied biology before. There are times of the semester when the workload is manageable and other times when it can get stressful, but once you know what to expect (particularly in second semester) it isn't as bad. In second year, the pace is stepped up a bit as a result of a double subject that is a core for Biomed students called Molecular and Cellular Biomedicine. I'm not going to lie, it's pretty tough, and stressful at times during the year, but looking back on it i found it was a very good subject and it exposes you (and in quite detail) to Biochemistry, Genetics, Cell Biology, Microbiology, Immunology and Pathology, whilst integrating these topics into themes such as Cancer. Contact hours aren't great, but don't expect them to be if you decide to do a science course. This semester has been my lowest contact hours at 17 (or 13 if i didn't have a prac or workshop).
How much time i spent studying, as Russ said, really depended on the time of the year it was. During semester I just did as much as i could whilst balancing work and a social life. There is plenty of time at uni during classes to get work done if you use your breaks wisely. So i might have done about 4 hours a day, but only 2 of those might have been at home. However when it gets to SwotVac, i go into a bit of a lock down mode and do quite a bit lol.
As for difficulty of the content, well, I'd say it's fair in the most part, considering that the top 5% (now top 2%) of the state are in the course. I don't think the content is difficult per se, but when you add the sheer amount of it, and the pace, it can be a little difficult at times. That being said, i find it very intellectually stimulating.
I find the course content extremely interesting. I also think second year is FAR better than first year. First year in a lot of ways is all about getting everyone up to the same level. If you are interested in science with a medical underpinning you will absolutely love it.
Overall i absolutely love Biomed, and i find it interesting and most importantly, fun. Yes, there are a lot of times during the year where it is stressful, but at the end of the day, they are trying to prepare us for entering graduate courses (such as med, dent & physio), as well as honours and research. On a side note, if you are interested in doing grad med, then the course content in first year is very good and helped me get a pretty good score for GAMSAT.
If you are interested in health science then i can't recommend it more. Good luck with whatever path you chose and as Russ said, I'm happy to answer any question you might have.
