Take it again. I took it the first time and got a 27. My high schools average was a 19... I took it again and got a 29 then. I got accepted into all the schools I applied too. I think they were, UW Plattville, Bradley, South Dakota School of Mines and Tech, Michigan Tech, and Milwaukee School of Engineering. There might have been 1 or 2 more, I can't remember. I ended up with $12k a year based on grades at Michigan Tech, and it's a great school anyway, so I went there.
But take it again and see how you do. You can probably get a 29 or 30 on it.
