Hey man. Yeah they are crazyily hard sometimes. One of the things I do to easily elminate 1-2 answers is by immediately looking for the smallest or largest (whatever one is most obvious)....and then looking at the answer choices and immediately elimating wrong ones. From there, its usually down between only 2 angles.....so I just look at those to see which one is bigger and ignore the other 2. It works pretty well. I've have read on these forums of people using the "nose" strategy......idk how that works though. Anyone care to elaborate?
