Can you please explain how the test is scored. I am a little confused. For example, the total number of questions asked in CR is 116. And if someone gets 72 questions right, and after subtracting the number of incorrect questions, the points are 64, what is the score ?.

You’ve got your numbers wrong. There are 67 CR questions. You get +1 raw score point when you get a question right, –0.25 when you get one wrong, and +0 when you leave one blank.

You should check out a scoring table to get a better sense of how it works. Here’s one.
