Nice Question Bank | But relevant ?

I got MGMAT CAT's and tried full length tests there. Honestly, Quant was brutal. One eye off and they start giving you PS, indicating, you did previous question wrong. There is definitely a lot of difference when we compare it with GmatPrep official question bank but if you are just casually doing them, they do give a run for your life .
For verbal, i find their RC's good enough. SC is on same level like GMATClub Tests but CR was a bit cranky there. Sometimes, i felt like the arguments were not as strong as they are in official Gmat guides.
IR was fun though. They are identical to official guides and i find them pretty much fun to solve.
