Sandra_Academic Writing_S2012

I just finished writing the abstract for my paper (Topic: Talent alone does not make an athlete). I think the link provided on Moodle about abstract writing was quite helpful (http://www.ece.cmu.edu/~koopman/essays/abstract.html), however I am not  100% sure whether we are supposed to write the abstract in present or past tense. Does anyone know? I wrote it in the present tense, because some other source I found on the Internet said so, however I am not quite sure about the reliability of this source ;-) I am glad for all help!  See you tomorrow! Yours Sandra
