Did the trick
I am not a big person by any means, so these things tend to have more potency on my body. I used this so I could better study/memorize for my CompTIA exam. My first day, I only knew one. First time I used this, I felt like I was noticing everything while still focusing on what I was doing.<br /><br />Ultimately, I passed my test with almost a perfect score. I discontinued use after that. I will pick it back up for preparation for my next exam.
