I took GMAT prep classes and the professor told us that experimental questions often don't have the correct answer among the answer choices - I have never seen this info anywhere, is this true?
I understand that those questions are not scored.. but if you solve a problem and can't find the correct answer - you re-solve it again, thus losing time.
thanks in advance and good luck to all!
The inclusion of experimental questions on the tests is intended to gauge the % of test takers that are able to solve them right and afterwards include these questions at the correct level on the regular questions bank. Otherwise, it doesn't make any sense to include a question without the right answer on the alternative choices.
