Any Introvert studying?

I am in a school that I do not like much and eventually I should study and obey their laws , I do not study usually except a very little amount and when it comes to the quizzes I study.
Usually I am tired and even when I study I am tired,.
Any advices or tricks for such a case?
Keeping in mind I am single and live very far from my family and have no friends generally maybe you can say I am an introvert.
And people who I am forced to deal with such as group works I d not get familiar with them and get usually in the last period hurt from them
