Just did my first subject review on BIOM20001. Feel free to give me feedback or ask me questions. Will probably do one for BusFi soon
I can understand your grievances with MCB and it certainly can be said that the detail involved in the subject is overwhelming. At the time, as I think I wrote in my review, I was quite frustrated by the focus on minutiae. What I suspect you will found, however, is that a lot of what you covered in MCB does pop back up later on, and despite having long forgot a lot of the details, the framework will still be there. You will find that to be invaluable in the coming years.
One of the sad realities of biomedicine is that it is very much focused on learning the details of things. I'm afraid to say that a lot of what you cover from now on will be more like MCB than it will your first year classes. I know you're disappointed in the subject, and perhaps your result too, but I'd really encourage you to try to be a bit more constructive about the experience and think of some ways to better cope with a subject like MCB. You might find that helps you a lot over the next couple of years.
