<p>I checked in Wikipedia that a No. 2 Pencil is actually 2HB. I bought a 2B pencil!!! Oh no! Can I still use the one I boughtt?</p>
<p>You can use whatever (pen, pencil, etc.) as long as the bubbles are filled. I used a mechanical pencil on May 7th and got 2280 and 800 math which means that even the grid-ins accept mechanical pencils.</p>
<p>My son “got caught” using a 2.5. His scores still counted, but college board sent him a “you better not pull this stunt again” nastygram. </p>
<p>No lie. This really happened.</p>
<p>No. 2 = HB = any regular pencil or mechanical pencil (despite the frantic enforcement of the “no. 2 pencils only” rule)</p>
<p>Technically, you should be fine. But the better question is why don’t you just use a regular pencil?</p>
