Thanks everyone for all your kind response. One never how helpful people can be unless you open up. I really am grateful to all of you. On another topic i'm currently writing my SOP, Though am for fall 2014, i have started preparation in earnest, i want to give this my very best in all area- gre, sop, recs, etc. On the sop, i wrote and presented a seminar in my final year, albeit that it was at the departmental level, would adcom see this as anything positive? Also because i lacked wet bench research experience, throughout my senior year and even currently, i have been reading journal articles on cancer research, i thus have an extensive knowledge in the field though theoritical. I want to incorporate it into my sop but an having a hard time on that. Finally i'm applying to Harvard BBS, Vanderbilt QCB' UT Southwestern basic science and KAUST Bioscience any general idea and suggestion that would be of help to me would be appreciated.
