a mix of both positives and negetives

I found this club really really helpful right from the time i joined. The questions are of HIGH QUALITY and the concepts and answer explanations are quite clear. However, there are times when some difficult questions are not followed by proper explanations and it gets a little difficult to understand the questions and reason behind getting a wrong answer and this is especially true for the problem solving and data sufficiency questions. Overall, I am completely satisfied with the variety of questions that are available in verbal and quantitative part. The best part is that these tests can also be taken as quizzes and selection can be made by us. This is a very good platform for test takers. kudos to gmat club. :*
