Interesting mentality questionnaire

So today in my keyboarding class, my teacher gave us all a questionnaire that would reveal a person's brain dominance pattern.  It says at the end that the brain is divided into the left and right halves, and that each one is applied for different things.  The supposed "goal" is to be whole brained, by that it means to use each half equally in situations in every day life.  I find this pretty interesting so i wanted to see what you guys thought of it too.  Don't think that i cheated lol because i honestly answered all the questions without knowing what the point of it was.

below are the images of the questionnaire

Is this some sort of scam, or do its results have relevance to finding out about your strengths and weaknesses?
try it out and tell what you think.
