Oops, forgot to say, Im doing an undergrad degree, physical sciences. Was doing BSc physics.

I'm in 3rd year, doing a resit because i haven't earned enough credits to go into 4th year honours. By taken seriously, i meant because of my circumstances, as i failed a couple of courses. :(

I was doing a physics course, but due to a couple of bad years, I wasn't on track to come out with a half decent honours degree. My advisor said I would be better changing to a physical sciences degree, which I have done. I would really like to do a PhD, and my heart really lies in quantum mechanics. The only thing is, I'm not sure if I would be taken seriously. Could I get some (honest) views?
