Wouldn't say that it wasn't tough, just that I wouldn't think that my grades, etc were THAT great. Altho MrSWO said on the military.com boards that the applicant pool is larger than USNA (and fewer spots available), I had no idea that was the case.
SATs aren't that bad...just get a study guide or 2 and go thru the exercises in there. The math is very basic, mostly algebra, trig, and geometry, which I'm a lot better at than calculus. You should be taking the toughest classes you can (AP and honors) and if you're doing this, whatever you've learned in school by the time you take the SAT (probably midway thru junior year) should be more than enough for the test. Might want to even brush up on stuff you learned freshman and sophomore year. For verbal, vocab is nice but if you get grammar, etc down flat you're good to go. Also take SAT 2s and do well on them, since it does a better job than the 1 of showing what you've actually learned in class, as opposed to natural intelligence.
You should probably submit your scholarship as early as possible. Go to the NROTC website at the beginning of your junior year and ask them to send you a brochure and pre-application. Just fill it out and they'll notify you by mail for everything after that--they'll send you your regular application when it's time for that and after they get it you'll get a letter asking you to set up your interview appointment. I sent in my full application I think around December of my junior year, and my interview was in April or May. I got all my stuff in pretty much as early as possible, you should probably do the same unless your grades are slipping and you need an extra semester to pull them back up.
Anyway, if you have any more questions about the scholarship process or anything else feel free to post here or on military.com, or e-mail me at afowler888@aol.com. That being said, you're just a freshman so you don't need to start seriously worrying about this yet; by this time next year you should MAYBE be requesting the pre-application materials. Just sign up for the toughest classes you can, get good grades in them, and you'll be fine.
Good luck
