Help

I wanted to get into biomed or something related to biology but I didnt get the rank score for the required programms but I did get the rank score for health science but I didnt apply for it.

My parents just told me to do commerce instead, so I did and I ended up hating it. I'm half way into semester 1 and now Im thinking if I could take up a BSC with my commerce degree in semester 2 and apply into health sciences from next year?

or, if I were to drop out rn, attend all health science lectures and then apply next year according to my year 13 grades.

what do you think would be the best? or do you think this is possible at this point
