These are for assured scholarships. As long as you apply on time and have the stats, you get the money. For instance, at Bama, your child would get free tuition - including out of state tuition. And, if your child majors in Comp Sci or Engineering, he/she'd get an additional $2500 per year.
However, some schools have competitive scholarships, but there's no guarantees with those. It's ok to apply for a few of those, but don't depend on them.
