Yeah I knew where I sat GRE wise. I didn't really give myself much time to prepare for them. My letters of rec are coming from professors who know my work individually, in groups, and in extracurriculars. Plus they have affiliation with the schools I'm applying to, either receiving their PhD there or teaching there so I'm really hoping that can give me a nice boost. Rough time for petroleum but I don't want to quit yet. Thanks for your help!
