12am too late to go to sleep on a school night?

My parents keep giving me a hard time because I go to bed at like 12am and have to wake up at 7. Is that bad? Because it doesn't really bother me...

I usually feel bad unless I get 8 hours but everyone is different

IF your GRADES ARE GOOD .. THEN IT SHOULD BE OK

It's always best to get AT LEAST 8 hours, but some people seem to be able to function properly on less.

if it doesnt bother you then its fineI sleep around that time, sometimes later. if I wake up in the mornin and feel tired then I'll just sleep half an hour earlier lol.

if it isn bother you and you are doin really good in school, it shouldn be a problem, I went to bed at 12 and got up at 6:30, and I done fine at school, I was dead tired when I woke up, but I can go to bed at 9 and still be tired, im just not a morning person...but if all is well at school, they shouldn have a problem

It all depends. If you're doing real well in school, then your parents shouldn't have a problem with you going to bed at 12.
I'm not a morning person but, I try to get to bed early but, that doesn't happen for me. That's because I'm in college and I stay up to do my assignments or brows the internet. If going to bed at 12 doesn't bother you, then you should be okay. Just try to get at least 8 hours of sleep if possible. Everyone is different though.
Also, if you're getting good grades, then I wouldn't worry about it.
