The Placebo Effect

I recently took a psychology class, and in that we often looked at the placebo effect and how it can have an impact on a tests results. I personally think that the placebo effect can be completely effective on a test. The brain is powerful, and I think that it is more than capable of convincing the human body that something is what it is meant to be. I personally think the placebo effect can easily do what it is supposed to do.
