Penn State also asks for SAT/ACT scores, but it is optional. I got a 1260 on the SAT, which I thought was decent at the time. However, this was back in 1992 and I remember hearing that the SATs were changing shortly after I took it. I don't know if this turned out to be true, but at the time, guidance counselors were telling us that on the "new" SAT, our score would probably go up 100 points. Anyway, I doubt that an ADCOM is going to realize that I took a different version of the SAT than the one that the "traditional" applicants took.
Anyway, just that fact that they ask for SAT means that it is a consideration for the ADCOM. If it wasn't, then why ask for it at all? I wonder at what point it is better to leave that question blank. Obviously if you got 800, leave it blank. What about 1000? What about 1200? Who knows.
