Sorry to be the bearer of bad news, but it's unbelievably difficult for GMAT test-prep companies to copy the style of the GMAT, and there really isn't anything out there that perfectly mimics the GMAT verbal section, other than the GMATPrep tests
. MGMAT arguably comes closest, and I agree that MGMAT verbal tests don't really feel enough like the real thing, either.
One thing you could do is purchase the GMATPrep Question Pack, and give yourself randomized sets of verbal questions from that resource to try to mimic the test experience. It isn't perfect--especially since you won't get a scaled score and your "test" wouldn't be adaptive--but at least it would feel more like the real GMAT, since the questions would be actual retired GMAT questions.
I hope this helps. Good luck with your studies!
