I was averaging a 128 on CARS across my practice exams, but I got a 126 on the real thing. I attribute that to one very long and boring passage, and I made the rookie mistake of spending too much time on it (probably not even getting it right), and having to guess on the last couple CARS questions. As for the other sections, I thought I did great on chem, did OK on bio, and did terrible on psych (ask anyone from the 3/31 test date). Surprisingly, I got only a 125 on chem, but 127s on both bio and psych. I guess that has to do a bit with the curve as well. I'd say don't feel too bad if you don't think you did as well as you should've. You probably did just fine, or right around what you got on AAMC practice exams. Best of luck!
