Like most of you, I came up right-brained on both of these tests.
Here's another one I found that, I think, does a better job of explaining how your left-brain/right-brain preference impacts your learning style, and also takes whether your are more visual or auditory into account.
This one requires you to download an app to your computer, which you may prefer not to do. I tried it, and don't seem to have acquired a virus, but use your own judgment.
(I came up slightly left brained and slightly visual the first time. The second time, (and the questions change each time you take it) I was still slightly left-brained, but overwhelmingly visual.)
So, at least as accurate as your horoscope.
