Don't all schools teach, RTFQ and RTFA. ?
I was always taught read the question then answer it in your head without looking at the answers.
Then read the answers given scoring through the one's obviously wrong. If one fits exactly what you have answered in your head mark it and move on.
If there are 2 that appear as if they are both right. Read them again and see if they are taking the piss or not. Then go for the nearest answer to what you were thinking.
