So I'm in Grade 12 and applied to a bunch of science programs for university. I'm currently thinking of applying to pharmacy school when I'm in second year. If I don't go with that, possibly graduate school or even medical school if I have the grades. Anyways, if I volunteered at a hospital (let's say 150 hours) when I was in Grade 12, will anyone even give a fuck? Is it worth it?
There's probably counselors, teachers, and even current pros you can talk to, all of whom will give you far better advice than anyone here can.
Having said that. I don't think volunteering changing bed pans (or whatever a high school student is permitted to do in a hospital) will do much for you besides a pat on the head. Did the volunteering do anything at all to increase your marketable skills? Did you really learn anything about pharmacology or the medical sciences? Be honest. Ignore the moral kudos you're looking for.
