Hello,
When composing or compiling multiple-choice questions, the choices for each question have to be clear, decisive, not vague and not so confusing as to have two correct answers at the same time, unless you do mean this and have it included in one of the choices saying for instance "Both A and C".
The questions should tackle and focus on the topics covered. Also, they must take up the assigned time minus fifteen minutes at least for review, checking and unforeseen circumstances.
Furthermore, the questions (and their relevant choices) should check materials learnt by heart, judgment ability of comparison and inference, as well as the spark of wit. Never must they be parochial.
Finally, such questions can come in as varied formats as possible, with or without illustrations.
