The worst thing about Scantron tests was when you skipped a problem and planned to come back later, but then forgot to leave it blank on the answer sheet. Then all of your answers were off by one, and you had to go back and erase/refill. Some teachers would let you finish with the error intact, and then spend extra time (without the questions, just the answer sheet) shifting your answers down. But if it was a standardized test, no such luck!
