good as a starter but not so much for real improvement. useful tool for putting and monitoring strict timings.
Many questions are written casually.
Solutions for multi source reasoning are available while writing the test.
the timer gets stuck many a times.
the score should be visible for the whole test otherwise what is the point of writing a "test".
although the purchase is quite economical but still not worth it..should be available for free for serious GMAT Club members.
the analysis part was a big disappointment especially for multi source reasoning questions as answers are not visible on the error log page and the questions have to be searched separately. I am happy overall but it needs alot of improvement.
