Use the answer choices to guide you. Don't just look at the angles without looking at the answer choices. At first it may be hard, but with practice you'll get fast at it. Don't spend more than 5 minutes on this section on the test. If you are choosing between 2 choices, then go with your gut. Its not useful to spend a lot of your time deciding between 2 choices on angle ranking because you can use that time to finish up and work on other problems of the PAT that will bump your score up more easily. Angle ranking can be one of the harder sections of PAT, but if you can do well on the rest then you will be in good shape to get 20+.
