I am having problems with this section, I don't think I learned it well in High School and also the books that I have gotten such as Kaplan are too simplified. Can anyone help me with this please. Also Can someone tell me how often this type of ques. show up on the exam?

Hi Naome666,

A lot of students struggle with counting questions. If you search the forums, you'll find lots of great questions, solutions and instruction here.

I'm going to go out on a limb and say that you may see 1 counting question on test day (maybe 0 maybe 2).

Cheers,
Brent
