I would not recommend that approach because of the grading penalties for wrong answers (as opposed to "blank" answers). I always advise my students not to guess at all, unless they can, somehow, eliminate all but two answers, which seldom is possible. Guessing between two possible answers puts the odds of the scoring in their favor, but guessing among several will definitely work against them unless they happen to get VERY lucky.
