Yes, if you believe your score is incorrect, you can request a rescore for your AP Exam. However, it's important to understand the limitations of this process. You can only request a rescore of the free-response section of your exam. The multiple-choice section is scored by computer, and the scoring is highly accurate, so resources are not available for that part.
To request a rescore, you must submit a written request and a fee of $30 per exam to the College Board by the deadline, which is typically in the fall of the year you took the exam. Your free-response booklet will be re-scored by hand by a different team of experienced graders. It's important to note that very few score changes result from a rescore request. The vast majority of the time, the original score is confirmed. However, if a scoring error is found, the fee will be refunded. Before requesting a rescore, it can be helpful to review your free-response questions (which you can request for a fee) to see if there was a clear misinterpretation or error in grading.
