Hi Faarzein,
I agree your background is atypical of MBA applicants and you will likely face some scrutiny for your decision to leave law school, your GPA, and also the gap in your employment. While UCLA is likely a reach, USC could be a near-reach, and Pepperdine and Claremont could be receptive to your application if you clearly state why you are seeking an MBA now.
