It occasionally happens for some people. I had one a few days ago where I got it back and it was a 15 PS, 10 VR, 8 BS. These scores are pretty ridiculous since i usually do about even on all of them(11-13 in sciences, 10-12 in Verbal). The Bio'd been bugging me since I remember a couple questions I'd missed though. That said I'd be pretty disappointed if the total ended up being about the same.
