I took the test, and honestly I thought some of the questions were a little hard to give a good answer to. I must consider though, no psychological survey is going to be very accurate at all to begin with with only 18 questions

You responded as a right brained person to 12 questions, and you responded as a left brained person to 6questions. According to the Hemispheric Dominance test, you use your right brain the most.

So yeah, something roughly around there I guess. I would have thought right-brain dominant to some uncertain degree.
