Guys do you know if in multiple-choice question you answered correctly just a part of the question (e.g correct answers 3 but you answered only 2)?
Will it count as a wrong answer to the question or will it count as a partially answered question?
Unless things have changed, if you were told to pick X out of some number of possibilities and even one of the X you picked were incorrect, you would get no credit for that question.
Pay very careful attention to the wording in this type of question. A big hint is often buried in the way the question is asked.
