One thing about the books of best colleges and the sort...
Make it clear to both you and him... collegeboard.com should be your best friend. It has all of the ranks, tuition, fees, acceptance, SAT scores, requirements, deadlines, etc. for every university. It is the status quo.
Which goes to point two... if you want to raise your SAT in math, there are two ways to do it. Taking the test again until you've reached your maximum amount of tries, and lots of studying in actual practice. What I mean by that is that the only way to better yourself for the SAT is to take actual mock SAT tests on your own. There's nothing to 'learn' for the SAT... just to learn how to take it. Most of that test is a gigantic farce where they just want to see if you were reading instructions as opposed to if you know how to do the test. Lots of fooler answers.
Trust me, it's worth it though. You want out of Maine, correct? The best way to do so is get high SAT scores and get into schools where your parents can't refuse the offer!
