They want you to buy their books, enroll in their preparation classes, and if possible, they wish you to take the le action ne plus ultra, sign up for help with one of their private tutors, which can cost up to $250/hour or more. And a group of us have pondered this, and independently come up with the same conclusion: The most probable reason for this is that the commercial companies have a vested interest. At least, most people who report on this forum say that. Some people's commerical scores do resemble the real GRE.īut MOST people score lower on the commercial tests than on the real GRE. The predictive validity of this conclusion is all but certain (n = 100000, p < 0.00001)."
All studies have been peer-reviewed, cross-checked, and double-blind executed.
HOW LONG IS THE GRE POWERPREP TEST SOFTWARE
"A 1-to-1 negative correlation between commercial test software and ETS's powerprep software has been unmistakeably and unimpeachably proven using regression analysis the sample set comprises thousands of cases spanning decades of research. The real GRE didn't seem to care, but on my Barron's practice CD tests, I definitely got like in the 600s for math both times.Īre you sure that GRe companies are really worst to measure our actual score? İn fact, these makes me demotıvated so I need the best straigth comment. In the verbal, my scores were the same on the Powerprep and Barron's, but because most of my math mistakes were from misreading the problem, I am as likely to get a problem wrong in the middle as the end. The algorithm that some of the test companies used is quite different from the real GRE's. There was another problem about a triangle inscribed in a semi circle that I know I got wrong because I just had to guess and move on (totally the right decision).
HOW LONG IS THE GRE POWERPREP TEST HOW TO
I spent like 6 minutes on it before realizing I was calculating the wrong thing (I was doing x+y, it wanted x+z kept getting these funky results even though I knew how to do the problem). In the math, on the real test I got caught up on one problem that I misread. Basically I lucked out big time, but I was so nervous I did the whole experimental section at the end because I didn't want to see my score. BUT, I should add, that on my practice tests the only questions I was really messing up on were the antonyms, and on my real exam the antonyms were so easy that I thought I had made serious mistakes and got sent down a lower track.
