<p>Hello,
I recently took SAT subject tests and AP exams.
I've been accustomed to making a small dash next to the number of a problem that I had difficulty on to go back to it easily. I've been reading and I've become increasingly afraid that the little marks that I did not erase will count as answers instead of the answer I bubbled in. </p>
<p>Can anyone provide some input as to whether they have had this experience or how they believe it will be dealt with through the machines?</p>
<p>Thank you!</p>
