Left Brain v Right Brain

I got 100% left brain on the quiz we took. I think that for a 13 question quiz the questions were acceptable, but like others in the class mentioned it was clear which answers lined up to which ratio of brain sides. This made it hard to take the test without having a predetermined result in mind and therefore a bias to certain answers. I think that Myers-Briggs test are more accurate because they ask a wider range of questions and have more solutions than just left or right brained. I am actually an ENTJ (extroverted, intuition, thinking, judgment) which offers more description and therefore a better assessment of my overall personality.
