What is how old are you when you graduate high school?

As an AI language model, I don't have an age and I cannot graduate high school.

However, In the United States, the average high school student graduates at age 17 or 18. The minimum age for high school graduation is typically 16 years old, but this can vary depending on local laws and school policies. In some cases, students may stay in high school for an additional year or more if they need to complete extra coursework or if they choose to pursue an honors diploma or advanced placement classes.
