Please Don't Join Princeton review !!Reasons:1. Each class consists of 2 hrs of lecture, which includes doubt solving time

. The class is always late by half an hour.
2. They only read the things given in their manual and ask you to solve the official guide yourself and then blame you for not solving enough problems and ask you to practice when your score does not improve even after 3 months of training.
3. They teach strategies that are easily available in books and internet. Strategies actually required for GMAT are not taught and whatever is taught can be easily understood by reading available books and browsing internet.
4. They have an online tool... which everybody has .. they clam to have unique computer adaptive tests... nothing unique ... better versions available at other international institutes .
5. Refer Kaplan and Manhattan review which are far superior to Princeton Review's material.
*** Actually we all feel the need to join coaching class to get things done .. but truth is just get the books based on reviews on internet, register to some online tool that has 5-10 GMAT CAT tests, study everyday for min. 2 hrs, and practice giving full fledged tests and then review them.
All the best
