I have less than a week until the SAT. I'm not nervous about it - I know that if God wants me to do well on it, I will, and if he doesn't... then I won't. But I'm still studying like crazy for it.
Practice that I've done to date: 8 lessons of math (including some trig), 2 practice essays, and one novel read (that's my way of studying for the verbal sections - reading, reading, and more reading).
Keep me in your prayers, please!
