i did pp test the nite b4 the real test and scored 690 on it.
the next morning i took the real test. got 680.
note: some of the Qs on poweprep test came out from the exericses of the og book that means u will see some qs that u've seen b4.
therefore, ur pp test might be inflated a little bit. Since I only did the sc on the og and there were about 3-4Qs that I've seen b4, I think my pp2 grade wasn't inflated that much. But, overall i think it is a good indicator if u have not covered the og book from page 2 page!
