Why not? What is wrong with spending an hour a day (or 6 hours a day, for that matter) davening?
Because she has a schedule to keep that prevents her from doing so.
Umm… religious rights?
A private school is not under any obligation to make religious accommodations. Or do you think that her yeshiva should allow her to start her day at 1PM if she wants to spend six hours davening?
Yes, it can be done out of SE… but why should it be?
Because it’s interfering with her school schedule.
