Idk about other countries but we had girl in our class that was like 23 or something when we were 15/16 so yeah I think it’s possible but I don’t know in what countries
I my country there are cases of grandmas and grandpas who didnt get to graduate elementary/Highschool/college are attending schools and are passing with flying colors. Some of them have to work when they were young to feed their siblings, now they wanted to at least graduate or just get a diploma
Can someone older actually be allowed to re-enroll in high school?
