Ugh, I was actually looking forward to MCB until you said this - it's most likely going to determine my major. I really despise mindless rote-learning. =_=
Problem is that most of 2nd year will be rote learning whether you like it or not. Anatomy, biochemistry, microbiology, immunology, pathology, cell biology, pharmacology, genetics (in MCB at least, not GENE20001) all of them demand you to memorise all the small detail. Physiology has less emphasis on rote-learning and more on application, but I still found myself rote-learning a hell of a lot from the pre-reading before the exam.
I think that out of all the selective subjects I did this year it was Microbes that needed the most amount of memorisation by far...you'll investigate pathogens that cause gastroenteritis and you need to know stuff like symptoms, how long it takes for symptoms to appear, whether its acid-resistant or stable, what toxin might be produced, the whole process of pathogenesis, laboratory diagnosis, how to treat it, what animals or sources it might come from...etc. But don't let it put you off because if you're interested it's quite easy to memorise
