Did you take one of our courses? Have you spoken to your instructor at all about your situation? If not, email him/her to ask for advice.
You can also read this article and do the analysis described to try to figure out why your score dropped. (If we can figure out why, then we can figure out what to do about it.)
http://www.beatthegmat.com/a/2009/10/26 ... went-wrongIt's not unusual for people to experience a score drop on a 2nd test. There are a lot of things you're trying out for the first time; many people will mess up the timing and/or other things on the 2nd test. (That's one of the reasons we recommend that students take their 2nd test halfway through the course, not at the end. Just a piece of advice for others reading this who might be in a position to avoid making the same mistake as this student.)
Most of my students take
at least 3-4 weeks after the course to review, and many take a lot longer, so it's not unusual to continue studying for a while after the course - don't worry about that. :)
