What's the consensus on the usage of fill in the blanks and true/false questions in a single quiz? I know these should be kept to a minimum in favour of multiple choice questions (as this type of questioning works better). I ask because I'm writing a quiz on the US Constitution and am using two true/false questions and a fill in the blank.

Different categories have different rules, and some editors will allow a little leeway in those rules and some won't, depending on the circumstances of the individual quiz. I'd suggest you write to an editor in your category and discuss it. Then when you submit your quiz, mention this in the author's note so that editor will continue working with you.

Thanks.
