Most 16 year old would be going into 11th, yeah. 16-17 is 11th, 17-18 is 12th. By the time you graduate 12th everybody should be 18. Unless they doubled up to graduate early, but...

So if she's in 11th, it'd be honors History more than AP since AP tends to just be for 12th grade. Wanna have them in class together again? :)
