How old are you in tenth grade?

Answer 1

Usually 15-16 years old (start at age 15 and turn 16 sometime during the year or the summer after), but you could be as young as 14 (if you started school early, skipped a grade, or if your state has a later cutoff date that allowed you to start kindergarten at age 4 instead of 5) or as old as 17 (if you were held back a year).
