GMAT CLUB TESTS 90/100 On a realistic scale

Firstly I would like to say that Gmat Club is an extremely helpful and updated community. It has every information one needs about Gmat. Coming back to the tests I found Gmat Club test extremely good predictor of Official GMAT. It's one of the best gmat test experience one can have in the market. It's scoring system and questions are quite accurate in difficulty. To be honest one can rely on Gmat Club test.
Secondly GC test are somewhat difficult , not crazy difficult but there is a difference of 5-10%.
All in all it is a good practice and let's you know pretty accurate score and helps by letting you know where you stand.
To improve the gmat club test I would suggest adding more test so that i can be confident enough before giving Gmat as there are not many good gmat test Available in the market.
