No, I am not joking, I just read that in Barron's dat book, on page 192 it says,
"Although there are 90 questions, only 75 of them are scored, the remaining 15 are experimental questions that are scattered randomly throughout the pat, you will not be able to identify these experimental questions"
is that true???
I have seen that thread, but angle ranking is still too tough for me, I have been practicing for a long time now,but still get most of them wrong, oh well don't know what to do, probably will just skip all the angle ranking section and spend the 5 min in question I know I will get correct
