Help stray mark thing!

<p>Today I think I did well on my BIO SAT2; however, I am very worried because I left thin small marks on the answer sheet next to the number of each question I wanted to double check and I forgot to erase the marks. Someone told me that as long as they are very small and away from the bubbles the Machine will not detect them, but we all know that the SAT directs us NOT TO LEAVE ANY STRAY MARKS.
HELP PLEASE</p>
