Auburn’s OOS tuition is about $28k per year…That Presidential OOS merit award is only for $16k (and doesn’t increase when tuition increases each year).
That would leave you paying about $12k-15k per year while there for tuition and another $15kish for room, board, books, fees, etc…so about $30k per year after merit.
Alabama would give you free tuition (no matter how much it goes up), and ($2500 per year for CS or engineering)
Your remaining costs would be about $13k per year…if you take out a student loan for $5500, then your parents would only have to pay about $7500 per year. Quite a bargain.
