Stoicism and the Value of Education

Hello there, I was hoping to get some advice on how I can deal with my problems Stoically. For some time now I feel that I am not learning enough information at school, I have always had a thirst for knowledge and Stoicism has reinforced it. The problem is that my teachers in Global, Engineering and English do not usually have a good lesson plan or even one at all. I know that I should interpret the situation in another, more indifferent, way since I can not control my teachers but Stoics such as Epictetus enforce that “Only the educated are free”. This makes me feel that I should seek to get a better education and stop wasting my time in this one. What do you think of the matter? I would not like to continue wasting my 6 hours in school and make the most of it! (Please note that I am in the highest classes in my school for my grade)
