the angles are ridiculous sometimes. Heres what may help: keep in mind on the real exam were all going to either get lucky or not in terms of angles. But look at the answer first, if 3/4 of the answers start and end with the same answer, and the the other choice is obviously wrong then you can start eliminating. Also, don't do angles at 4 a.m. after a full day of studying your brain is going to be mush. I was getting 19's on my first 4 CDP tests and going over by like 15 minutes, and I took a break for 2 weeks. The next time I took it I got a 20 and had ten minutes to spare. Take a break, something might click.
