Definitely worth it!

I purchased the GMAT club tests and I have to say that the questions were absolutely brilliant. There are about 1500 questions and I liked the fact that I can choose what mode I want to practice in. So I did CATs, quizzes in practice and exam mode. Could filter topics easily. All the error analysis helped me. I didn’t have to maintain an error log, it was all available there in various formats and with various filters. Quant questions are challenging and well rounded, covers everything. Verbal I feel is not like the official questions but never the less good for practice as the required concepts are tested. I feel like it’s a must do for quant.
