GMAT Club Tests (730, q - 49, v - 41)

The GMAT Club Tests, especially the quant ones, are amazing. They offer a great practice, with an option to solve these in a practice mode or exam mode. The exam mode is timed, just as the real GMAT, and the software feels very similar to the actual GMAT. Each questions has its own explanation as well as link to the forum where the question has been discussed. In addition, you can analyze your weak areas, and concentrate on solving questions in that particular area. The quant was very helpful in helping me scoring a 49. With more time and practice, I am sure I could have got a 50 or 51. I'd definitely recommend these tests if you are scoring in mid to high 40s.
