yea i tried the hill thing but on CDP i'm getting 1 maybe 2 points higher so like 10 or 11 but i'm taking double the time so I dont know if its worth it, I just did one of the kaplan and got all of them right seems so much easier, all the ones i'm getting wrong on CDP are seriously 2-4 degree difference and are upside down or whaterever, is CDP alot harder on angles than the real thing?
