I have just taken a test "The Brain Test" and got the following result: 
Left-brained
Most left-brained people like you feel at ease in situations requiring verbal ability, attention to detail, and linear, analytical ability. Whether you know it or not, you are a much stronger written communicator than many, able to get your ideas across better than others.
It's also likely that you are methodical and efficient at many things that you do. You could also be good at math, particularly algebra, which is based on very strict rules that make sense to your logical mind.
