Hi.
I didn't get into Medicine (4-6 weeks study before exams tend to mean you don't do well in your final high school exams! Still, I made it into the top 3% of the state!)
Then when i could get into medicine, I decided I prefered to be a physio because I could help on a more personal level, with less time constraints and responsibility (like if I make a mistake, someone lives or dies!).
But why would you want to be a biologist - when you could be a physio?!?!?
