Hi Guys, admittedly I searched for this topic for only a couple of minutes, so if it's been answered (which on this forum pretty much everything has) then apologies.
My question surrounds the difficulty of moving one's score, specifically as you move up the curve. Does anyone know or is there any information out there on how much harder it is going from a 680 to 700 vs. 600 to 620 - those 20 points aren't earned the same way, correct? I know the test is adaptive and it's all about how you start so that you can get to that peak level, but I wasn't sure of the nuances and was hoping someone could shed some light (or a link) to the discussion around this.
Reason for me asking is I got a 680 and want to take it again because I think I can do better, but before I invest another summer I wanted to make sure I knew as much about the mountain I was going to climb.
thanks
