      Yes, I would most likely complete this question. Although, it depends on the situation during the exam. If my overall timing during the exam is reasonable and I feel comfortable with the question stem and content, then I would try to complete the question.

      Typically, I get three or four hard questions, that take me three to four minutes to complete under exam conditions. It is important to get these right to obtain a high quantitative score. I also make sure that I able to complete a good number of questions in 30 to 45 seconds, and allocate that time on the really hard ones.
