610 again even though I went from 36Q to 38Q and 34V to 36V

I can take the class again for free because of their better score guarantee, but my spirits are very low. I wen...

The truth is that GMAC has changed the test without informing the test takers.I saw 5 EVALUATION QUESTIONS in the critical reasoning section of verbal on my test. And this was unprecedented. You need to work harder to pass the verbal test these days. Further,most of us don't have problem in quantit...

It might not be Kaplan's fault, not like i know either way, but I think the verbal is so oooooo much harder and there aren't any practice materials out there yet because no one saw the change coming, I wrote the GMAC people. I'm not the only one out there dumbfounded, so dont blame kaplan, blame GMA...

I think everyone should write GMAC and express their concern! I have and am hoping others will too. GMAC needs to take responsibility for this as it's unethical to change the test suddenly. It's unfair to not provide test takers with material if they're going to make a substantial departure from the...
