You cannot compel her to learn.
If she is incapable of learning you cannot do anything on that.
Moreover this may be frustrating you but it is your fate, you have to accept it.
If you try to do anything that enrages her or provokes her then she may resort to all types of false criminal complaint against you and your innocent parents due to which everyone will be suffering with court cases.
Look at the things in wide angle, you will get convinced and start living happily with her. Her education alone is not everything in life.
