Well,what can i say.....Quant is not bad at all,especially at general stage of the preparation.
Quite good skills building questions.Quant scores were closely enough consistent with my official GMAT scores.
Verbal is a problem.I am not native,and my command of English is sensitively weak.I scored in mid 30's in Verbal parts of 800's CATs -consistenly.Actually,i would be glad to score even 30 in official test.Unfortunately i scored pathetic 23.
Bottomline -good for "general" math.Verbal part is very weak.Confidently deduct about 10 points from your verbal score.
Saying that i would like to underline that no test company out there has been able yet to come close enough to the official GMAT verbal questions.Believe me,i saw the beast!:) So,what was said about 800score verbal part is quite relevant to almost all prep companies on the market.
Hope,you do not mind my English:)
