<p>Well, today while I was filling up my economics answer sheet (the personal details). I realized that I forgot to fill up the bubbles for the ''serial number'' of my AP chemistry exam...</p>
<p>I seriously almost shat my pants when I realized how stupid I was...I asked the AP guy in our school and he said it shouldn't be a big deal...</p>
<p>Any information by anyone that confirms that?</p>
