many many people.....in my opinion the PAT really doesnt do much. A great score (20+) wont' really get you in...but a crappy score (16-) could potentially keep you out...its not your 19, thats a good PAT score....a 16 in QR and 17 in Gchem like me...now THAT will keep you out...good luck
PAT means crap for most schools and besides, a 19 is really good on the PAT. I have gotten into schools and invited to interviews everywhere i applied to (except UMDNJ...what the hell is their problem?). I got an 18 on PAT. I know people with 17, 16, 15, even 14 on the PAT who have gotten accepted. AA and GPA is way more impt than PAT for most schools.
