I graduated with a B.S in Physics this passing May. I applied to many graduate schools for nanoscience, however only one accepted me "provisionally". My GPA was lower than a 3.0 (2.8). So, now I'm stuck with a B.S in Physics and I'm not going to graduate school (I can't afford it). I really have a passion for Physics, and I want to have a scientific career in this field of science. Any advice? I'm studying for the Physics GRE, hoping that if I get over 50%; this will offset the low GPA.
