Well, this seems like the place to introduce myself and tell my story. I've been a Princeton Review teacher for six years, starting with SAT, then branching out to a bunch of other test types. In late 2007, I decided to add GMAT to my repertoire, and I got trained and convinced my office to pay for me to take the test. I already taught the SAT and the LSAT, so for the GMAT I basically just had to learn Data Sufficiency, which was fun, and basic CAT strategy (first few questions count a little more, etc.). Then I went in and took the test at the very beginning of '08 and got a 770, and I've been teaching ever since!
I've been away from the GMAT for the past few months, mostly focusing on LSAT for the June test and then MCAT over the summer, but I'll be doing a few of our live online GMAT courses soon (one starting on Thursday!), so I'm here partly to get back in the swing of things for my upcoming courses and partly because I think talking about big standardized admissions tests is fun.
