It all depends on what grade you're in. Most people graduate high school around 18 or 19.
To determine how old you will be when you get out of high school, we need to know how many years of high school you have left. In most countries, high school typically spans four years. So, if you are currently 15 years old, and assuming you have all four years remaining, you will be 15 + 4 = 19 years old when you graduate from high school. However, it's important to note that the duration of high school can vary in different educational systems, so it's always a good idea to double-check your specific school's requirements.
