bekitzur, i understand that you are very bored in class, but maybe this is just HaShem testing you to see if you could fight the boredom and really focus on what the teacher is saying. Torah is very deep, you are never done learning.
you could also just respectfully speak to your teachers about this issue. Im sure they will be happy that you spoke to them and will help you. if you find more girls who feal the same way maybe you can speak to your principle and make make an even higher level class.
if you feal that the teacher is very easy or going to slow, you can always look in the Chumash, navi, etc… for different meforshim (in english and/or hebrew) on what you are learning because Torah is very deep and there is so much to learn!
also ask questions and make apropriate comments on what you are learning in class.
These should make Limudei Kodesh classes more interesting.
