中等MATH-EXAM-002
On a multiple-choice item you have eliminated two options. What should you do next?
A. Leave it blank, because a wrong answer is always penalised beyond the lost mark
B. Compare the remaining two with the stem and answer; a wrong choice only loses that mark✓ 答案
C. Choose C, because C is correct most often
D. Change every earlier answer to the same letter
解說
Compulsory-part multiple choice has no negative marking. Once two options are gone, an educated choice is better than a blank. No letter is the house answer.
