What is the highest SAT?

Could you please clarify what you mean by "the highest SAT"? Are you inquiring about the highest possible score on the SAT exam? Or are you asking about the record-holding individual who achieved the highest score? Additionally, is this question related to a specific year or era, as SAT scores can vary over time? Could you provide more context or specify your question further, so I can provide a more accurate and informative response?
