[quote name='HowStern']^lol No, because, you only have to add 12 years. Because you will be 5 until you grad Kindergarten if your bday is after June. Like I said..If your bday is after June you will be 5 til after K then you will be 6 for Grade 1. 7 for grade 2, etc. 17 when you graduate senior year. So, it's 5 (your age throughout K) + 12 (the 12 years AFTER kindergarten...I'm not going to add 13 in addition to Kindergarten) IF you're bday is after june...
So, now I know 2 people who should have stayed in high school 'til 18 XD[/quote]
What you're saying is correct. I would know since I fall into the category of people who graduated at 17. I turned 5 in September right after starting kindergarten. (the deadline was January back then, but now it's September 1st in my state, so I would have missed the deadline by a few days if it had been instated earlier)
So basically anyone whose birthday is between June and September would be 17 when they graduate if they start kindergarten at 5. So roughly 1/4 of the people.
