SAT: Super Annoying Test

It seems everyone has gone "The NEW SAT" crazy. Granted I was younger then, but I don't remember such hype about preparing for the old SAT.
Apparently the only thing that's different is that they've taken out analogies (yay!), taken out some math stuff, and they've added an essay that has to be written in 25 minutes. The essay is no problem since all year in AP US History we've been pumping out an essay in 35 minutes every week, and I usually have some extra time. I told myself in January that I would take the March 12th SAT, but considering that the cut off date was February 7th, yea no.
Now there are like 2 SAT testing days still available this school year. One is right after AP testing (actually the day after my APUSH one), and one is June 4th. I SHOULD do the June 4th one because for the last couple weeks in May and all of June I shouldn't have too much school work since two of my three difficult classes are AP classes and they slow down after testing.

So, I really don't ultimately know what to do with the SAT's. I took the PSAT's last year as a sophmore and it really wasn't that bad so I'm not too worried about time or anything (even though the new SAT is apparently 50 minutes longer. Oh yay.)
I feel like I'm putting off taking it (I don't mean to), and I kind of feel a little stupid. I feel like I'm not taking the "right" steps for leaving high school and preparing for college.
What does all the SAT prep classes teach you anyways? How to use your time wisely? How to think about questions? How to answer questions? Thought process?
Well, really, I've learned all that from my AP classes. The AP tests are like the SAT's in my mind, only they're focused on one topic.
Ha! I've learned testing skills and I didn't waste my Saturdays in a muggy classroom.
