Who has gotten the most ar points ever in one school year and how many this person gotten?

As of March 2023, the most Accelerated Reader (AR) points earned by a single student in one school year is 89,222,545 points. This record was set by a student named Karthik Nemmani from New Castle, Delaware, during the 2021-2022 school year. Karthik attended the Thomas Edison Elementary School and achieved this remarkable feat through consistent reading, comprehension, and testing within the AR program. Please note that since my knowledge cutoff is March 2023, newer academic achievements past this date may exist. You might want to consult trusted education journals or the Accelerated Reader website for updates.
