What were jk rowlings grades?

It is not publicly known what J.K. Rowling's grades were in school. While she has spoken about her academic experiences in interviews, she has not disclosed specific grades or scores.

It's important to note that academic success is not the only measure of a person's potential or achievement. Rowling's success as an author is not necessarily dependent on her grades, and focusing solely on that aspect would be a limited view of her accomplishments.
