Question for the experts or those that have beaten this beast: how accurate is GMATFocus? I bought the three pack and have taken two so far and my score moved down on the 2nd test even though the results seemed to be better across the board.

Are the questions on GMATFocus much harder / algorithm more diffcult than the GMATPrep? It seems like the low end of the GMATFocus range is MUCH lower than what I was getting on GMATPrep.

I have the test in three days so I guess I'm freaking out over this. By the way, what a great resource this site is, thanks to everyone that contributes!
