Good .. but not perfect

it was a good experience overall. the tests prepare you for the hardest version, however it sometimes gets really tough , even tougher than the exam, which would affect your self esteem. the tests cover every part of the curriculum. but the answers are not well prepared, and sometimes the answers are very subjective (especially in the RC part), and they sometime don't make sense. I've recommended this course to other friends who had pretty much the same feedback. however, these tests are better than any other tests from other sources. my experience was with GMAC and egmat, and so far, my experience with gmat club was the best among them.
