Does the SAT scoring machine get confused with stray marks?

Question

When I folded my answer sheet, the bubbles I had filled out left imprints on the other pages. Now there are dark circles on my answer sheet. Is this common, or will this hurt my score?

Answer 1

Yes this could hurt your score. Any stray marks left on your sheet could be mistaken for answers. You should erase all stray marks left on your page, or you could receive a much lower score.
