I loved Physics and have a bachelors degree, I was popular at uni because of the ease I worked out all physics concepts. 3 hour theoretical labs I would finish in 1 hour and always get over 92%. It was a while ago but I understand physics better then anyway. I was the only person to get an A in quantum mechanics in 2nd year and I didn't study for it, the thing is I didn't get the right answer, I was missing pi, but I used 3 books to derive quantum mechanics from first principles... that seems to have worked.
