I went to school at 6 years, our schools were for 10 years, and at 16 i went to university. At the university with us were some 20 year olds, who went to school at 7 years, were not able to get to university in their 17, were drafted to army at 18 and came back. 20 year old being around 16-17 year olds did not cause any catastrophe.

20 year old who wants to study is not going to cause any problem for the public school either, it will even be beneficial for the class as children will see that studying is useful.

> teenagers are generally not allowed to make these choices, for good reasons

When they are not allowed to make choices, the parents are supposed to make choices for them, not corrupt politicians and bureaucrats.

>> the parents are supposed to make choices for them

Parents don't have any choice in this either. A child under 18 should be in full time education - there is nothing to choose, maybe except for the school they can be in.

>>20 year old being around 16-17 year olds did not cause any catastrophe.

I like that you shifted "adults with 15 year olds" to 20 year olds with 16-17 year olds.

That's a very fucked up thing to say, governments or random strangers from internet do not have a right to decide how parent raises his child. Do you even have a child?

It was just my own experience, if you want another example in early years of Soviet Union there were 40 year olds learning to read with 6 year olds.

And in general i don't see why any combination of ages should be a problem?

>>Do you even have a child

I do. And like I said, you as a parent have a choice about the kind of school you send your child into. You don't have a choice whether they are in education or not.

>>And in general i don't see why any combination of ages should be a problem?

When you were at school were there many adult students in your classes?

>>you want another example in early years of Soviet Union there were 40 year olds learning to read with 6 year olds.

Yes, 100 years ago in the early days of the soviet union the classes were offered to everyone to increase literacy rates. I can assure you that throughout the rest of history of the soviet union you didn't have adults attending primary/secondary school, gymnasiums or other types of schools for children. Soviet union had schools for adults from very early on.
