Some say grades are everything. Yes, it will help you get an OCI interview, yes some law firms won't look at you unless you have a 3.0, and yes it's not fair, but in law school someone has the set the curve and sometimes that someone is you. There are ways to overcome bad grades. Improve your other legal skills (writing, oral advocacy, leadership) and highlights those on your resume and in your interview. When you interview when asked about your grades say this,
"I have tried really hard in law school and done the best I can do. My grades do not at all reflect my potential as a lawyer and I recognize they are only a number. My grades do not define me as a person. However, I have many other skills that do define me as a person and as a lawyer and I think its those skills that will make me a great asset at your law firm, government agency, ect."
Something like that will work and show that you are not lazy, but also recognize that your life does not end and begin with your grades. Now if I could only listen to my own advice!
