What happens if you use a No 2 1/2 pencil?

<p>Does the entire scoring machine system crash or something? Just wondering. </p>

<p>Because they tell you over and over and over that you MUST use a No 2 pencil.
So, on the night before my SAT, I panicked because I didn't know what a No 2 pencil WAS (I think in HB, B...)
And I bought like 10 pencils in every shade</p>

<p>I'm pretty sure HB is No. 2... as long as you didn't use 8H or something you'll be totally fine. There's no point worrying about your pencil. ;)</p>
