I used to get only half right. But now I'm doing good and get 22-25 on CDP. I use the hill method. I'm scared of roller coasters, so which ever one has the steepest slope is the one I don't want to go on because it has a smaller angle, etc..... There are many ways to look at it. But try to incorporate the lines with something from real life. So if you haven't tried that yet... maybe give it a try? Also, this section should be quick. I've realized that the longer I look at the angles, the more confusing it looks. So, go with your first instinct. Also, when looking at the angles, look at the answers and do elimination. Good luck! 🙂
