I've done online school b4 and I didn't really like it.
Advantages- I guess it would be safer then being in an actual school, because of all the things that have been going on in schools lately.
You get more free time
It's good for people who do sports and other activities so you can do your work later
you can stay at home
you can do it anytime of the day or you could do it at night
Disadvantages- Your not in a school
you don't have teachers right there when you need them, sometimes you have to wait awhile b4 they answer back
work catches up on you fast
there aren't any clubs or sports
if the device your using messes up you can't turn in your work
