After having tried Gmatclub tests for several months, I can say that they are pretty accurate in the Quant section, not so much in the Verbal one.

I often find that the Verbal questions are not quite similar to the ones included in the Official guide. This specially happens with the RC and CR questions. In terms of the Quant section, I think that most of the questions are similar to the official ones, and those that you would never find in a real gmat test, however, teach you important concepts that are useful for other questions; this was specially true in geometry questions.

Another relevant point: the size of the question bank. I think it could be expanded to some extent. For retakers like me, some of the most atypical questions sound too familiar when you use the GmatClub test a second time. This makes me think, although I did not make any analysis, that some questions may be too similar. I have the feeling that in the Official guide there is a wider spectrum of questions, despite the higher number of questions.

Something that would be great to have: stats for each questions of people that really took entire tests, it often happens that the accuracy or time spent rates are tremendolusly biased due to people that spent 30 mins on that question. It makes the stats section useless sometimes.

Lastly, I think the scores provided are accurate enough, more than MGMAT for instance.
