Due to a minority program (I'm a minority, not an URM) at my law school (mid-T1 school in the Midwest) I was able to secure a SA position at a big firm in the Midwest this summer (the particular office I'm working at has over 200 attorneys and pays market to SA). I'm understandably happy and thankful for this opportunity. However, I can't help but look ahead and get a bit worried about 2L summer. My grades were not very good (below the median), and I have no desire to live in the Midwest after graduation (I'm from California and would like to return there). So while I might be able to bust my ass this summer and get an offer to return to THAT firm for 2L summer, I'm scared that all the California firms won't give me time of day, despite my work experience, simply because of my grades and school location.
Any advice? Other than obviously trying to improve my grades.
