The SATs are easy... And if you've only taken the PSAT then you've really got no right to comment on it, because they're certainly not the same (not that I'm saying the SAT is much harder in my opinion, but still... can't comment on how hard a test you haven't taken is).
I never studied, stayed up till 2 AM the night before, wrote a very mediocre (in my opinion) essay, and I still got a 1990, which was either 94th or 96th percentile, can't remember. Also, 1990 is the year I was born so... that's a fairly cool thing to note.
