GMAT Club Tests Review

I've taken about 3 tests and I think they're of very good quality. I've been taking Manhattan tests as well, but I think they are a bit tougher than the real question we get during GMAT. I am yet to compare it with GMAT Prep.

Apart from the question quality, they also provide a great performance analysis and links to forum discussions for each question. It becomes very handy to bookmark a question to revise it later and keep a error log here itself. They also allow me to analyze my performance of guessing an answer which I is great.

However, I think they can improve on explanations. For certain questions, most of which are in verbal, they've repeated the question itself. Although the 'link to forum' happens to provide the correct explanation most of the times, it is definitely an area of improvement!
