So what are my fellow Class of 2017ers planning on majoring in?
I'm thinking of either Patho (heard the subjects are pretty badly taught tho), Micro/Immuno or cell/developmental bio 
If you already have an answer to this I want whatever is responsible for your ability to make decisions so easily and ahead of time. O_O
On a more serious note though, you really should try to keep an open mind and wait until second year before locking anything in. BIOM20001 and BIOM20002 are great opportunities for you to get a taste of what each major is like and what you'd like to pursue. Following first year I honestly thought I'd be doing cell and developmental biology but this was by far my least favourite topic in BIOM20001.

At the very least you'll be able to work it out by deduction - I also know that biochemistry isn't my thing (but you'll feel better about it compared to first year chemistry) whilst I don't mind genetics and microbiology/immunology and hence keeping them both open with my subjects next semester (I'm taking MIIM20002 and GENE20002 alongside BIOM20002). I'm going to go out on a limb here and be all weird again, but despite what so many have said pathology was definitely my favourite part of BIOM20001. I've heard mixed things about the pathology major though, which makes me feel uncertain about pursuing it further.
