As you may have noticed, the system of filling in little circles with a #2 pencil is an old one — and far from perfect. The machines used to scan your answer sheets at the Educational Testing Service (ETS) are probably more sophisticated than the ones in your high school office, but that doesn’t mean they are flawless. Any errors in scoring may work for or against you, but — especially if you’ve made some erasures — it is possible that the antiquated (SAT word – it means old) technology may lower your score.
The College Board website warns (scroll to bottom) that your entire answer sheet is re-scored and that the outcome can raise or lower your score. The adjusted score is final. From my experience, few students receive a higher score through this appeals process, and few get their $50 back. If you score much lower than you expected, you may want to explore this option. However, if you’re simply not happy with your score, it may be time to accept the results and start preparing for the next test date.
