You introduce to you to an important examination.

this sometimes happened when i was still in school. the quiz or examination was different from what i had studied the night or hours before. what i do is that i analyze the questions well and see if i can atleast guess the right answers. however,i am also prepared to fail that particular examination or quiz. so, i won't feel too bad after getting the result.

well, i try to answer it as best as i can, usign my general knowledge. if you read a lot and study extra stuff, you can easily be prepared for "off-topic" questions
