I am extremely happy with my class from Princeton Review.

First of all, the teacher had been working there for 15 years and was
qualified to teach the LSAT, GMAT and SATs. I believe his expertise and
depth of knowledge (especially from the LSAT) made a lot of difference
because it allowed him to bring in other points of view and examples that
a straight GMAT professor might not know. In addition, LSAT has harder
verbal questions that Jake was able to use as examples, making the GMAT
less complicated and made discerning patterns easier.

Second, the class met for 3 hours a week, with homework and pre-work
assigned every week. It was extremely helpful for me to help develop a
study pattern and habit specifically around the GMAT. We also had several
full length CAT exams scheduled that gave me a good idea how I was
progressing and what areas I struggled with in a timed environment (which
were different than what I thought when I was practicing).

Finally, Princeton Review knows all the tricks. They have a lot of insight
into the exam and how to beat it. These little tricks and hints (about
timing, ways to approach problems, etc) were essential to my success at
the end of the day. In addition, they give two books with your
registration fees, one is the official guide published by GMAC (used for
homework problems only) and one written by the Princeton Review that gives
more practice problems and hints in detail. They also target the homework
based on what your pre-test score was so you don't spend any time doing
problems that are too easy or too hard for you. AND they have a guarantee
- not happy with your score, retake the class, no questions asked. I
didn't need to do it again, but it was really nice to have that safety
net.

Take this class, you won't regret it.
