Is there a significant difference between Power Prep CATs and GMAT Prep? I took the first GMATPrep 4 weeks ago. Since then I've taken 2 Power Preps then today the 2nd GMAT Prep. I've scored higher on each test than the one before, until today. I thought it was all the studying, but I'm beginning to think the Power Prep is just an easier test. I had much harder math problems today, and got a significantly lower quant score (40 vs 49 last week). I know the GMATPrep is supposed to be the closest to the real thing, which has me worried. Interestingly, I did better on the verbal on both the GMAT Prep tests than the Power Prep.
Anyone care to share their experience with these 2 tests?
