Just finished my GMAT and feel totally bummed coz I got a lower score than when I last took 6 months ago(640 q39 v 36, 620 q 39 v 36). Spent close to 100hrs preparing since last time, using OG, Princeton Review, Kaplan. Was unexpected that I'd score lower as I got a 720 in Power prep, but that was probably high coz of the familiar questions, being a re-install.
Any tips on what to do now would be greatly appreciated. Also, anyone know the general policy of the b-schools in looking at multiple scores when the latest score is lower?
