Well, darling, if you want a 70% on a 160-question test, you can afford to get 48 questions wrong. Anything more than that, and you'll be kissing that 70% goodbye faster than you can say "multiple choice." So, buckle up, focus, and make sure those wrong answers are kept to a minimum. Good luck, honey!
