You're a young 17 year old. You can sign on to owe up to over a hundred thousand dollars, if you choose to go to a private college, even though you can't smoke or drink until you're 21 (and, if you live in Mississippi, you aren't legally at the age of majority until you are 21!). Not only that, but it's a really hard debt to get out of and they will strongly pressure your family to cosign, which (should you fail) is a great way to wreck a relationship.
In fact, the 21 thing is pretty dumb anyway. You can get married, enter a lottery, take out over $100K in debt, or join the army and get killed, or gamble away your life savings, or buy gun ammunition, or sue people or get sued, but heaven forbid you buy a beer.
Next, schoolbooks. Ludicrously overpriced, to try to convince you to "sell back" your books at the end of the semester for a pittance. Colleges claim to love diversity - if so, you might consider not price gouging books to oblivion and making it harder for lower classes to afford college, perhaps?
