I am a student a tthe University of North Alabama.It is considered one of the best academic schools,and one of the best for low tuition.The tuition for here is about $1200 -/+ per semester in state and about $2300 -/+ per semester for out of state,depending on your circumstances.You can get FAFSA grants that pay for nearly everything.Call the registars office @ different Universities around your area and ask them.
