I have a good one, for anyone good at exams and good at cramming (I've always been for whatever reason...)
Sorry I didn't meticulously track my scores
These were all done the week before...
Manhattan prep Q:160 V:162
GRE Written practice test: Q:170 V:161
GRE Book practice test 2: Q:163 V:165
GRE Book practice test 1: Q:161 V:164
Kaplan I got 167 for quant, can't remember for verbal but ~162
I also did the Powerpreps a while ago (very informally too - quantitative at one point, verbal at another). Could only recover one quant score which was 162.
Actual Score: Q:169 V:170 (from the computer - haven't received AWA yet)
