This question already has an answer here:
I did very poorly in my first two years of college but I still want to get into a prestigious graduate program. The reasons why I did poorly are complicated and personal and certainly nothing I would want to share in my application.
I am considering a possibly risky route into graduate school. Namely, auditing classes at the university I would like to attend and then reapplying after a semester or two. This way I can demonstrate my abilities directly.
Obviously, the success of this plan depends on the quality of my work while auditing. Assuming the quality is high and I can develop connections in the department I am interested in (physics), is this a viable route? Or is it totally unrealistic? It is worth noting that I am in the upper 90th percentile in the physics GRE.
