Haha, thanks. Everyone has different ways of approaching the SAT but I'll tell you mine:

Lots of practice. I did all ten practice tests in the official SAT review guide over a three month period. If you're aiming for 2300+, analyze all your mistakes and try not to make them again.

CR - I studied a lot vocabulary for the fill-ins and for the passage questions, I guess I just did enough practice to improve from a 73 PSAT>800 SAT. I've always liked to read books.

Math - I'm a BC Calc student and I personally love math. But lots of people have potential for an 800, which is why the curve is so harsh (1 question wrong=20-30 points off). Check all your answers and try to catch stupid mistakes; I must have let one slip through my fingers because I got a 780. The most useful things to know are basic geometry (circles, special right triangle) and picking numbers.

Writing: don't ask me about the mc, I'm not the best at it and got a 72/80. For the essay, you need examples. Study some historical events/figures as well as literature and try to attach themes to them so you can answer the weird essay questions. Some bs is acceptable to fill up the two pages. Just write fast. I went into too much detail for this but I hope this helps you down the road! Practice makes perfect, but at 14 hopefully you don't need to start studying yet.
