Well, different schools are going to have different qualifications and different score requirements. Back when I took the test... *ponders* Which was a good while back... I believe the test is still graded the same. The Maximum score was 2400 points compromised of your three core sections of Critical Reading, Writing and Mathematics. ( 800 points per section. ) A Score of 1280 would be failing to most schools, sadly.
Most of your classes would be entry level and wouldn't count as college credit. You'd have to do some studying! I would recommend you seek out a tutor or some online help and brush up on some skills or take some college entry level classes to help you out. With some hard work and effort, you could turn that around in no time! No need to let that score haunt you forever.
It happens, sometimes people are really intelligent and very bad test takers.
It just takes hard work, dedication and applying yourself...
