The test definately is geared to determine your ability so it will get harder but don't just think because you have easy questions that you are doing poorly. On the quant, I remember getting absolutely blasted in the middle of my test (first 10 were easy, next 25 brutal) and my last 10 or so were super easy. I ended up with a 48 but thought I totally bombed it.
As for the Verbal breakdown, the books I've read said be prepared for an even breakdown of RC, SC and CR. You will typically see 4 RC (three short, one long passage of 12-14 questions) so if you are watching time remember how many RC you have left so you don't panic at the end.
