I took the test today. I only really practiced for the quant.
In the order of when I took them, over the course of about 3 weeks:
Powerprep I: 160Q 160V
Manhattan 1: Q159
Manhattan 2: Q160
Manhattan 3: Q160
Manhattan 4: Q161
Manhattan 5: 159
Powerprep II: 161 V 161Q
Magoosh estimate: 158-163Q 158-163V
Actual GRE, taken today: 164Q 162V
I felt like I was bombing the thing in the test center. Expected sub 160 for both. Ended up doing better than any of my practice tests.
Good luck!
