Can I stop attending class?
Why are you going to stop attending class?
I don't understand the point of this class, I'm not required to attend it
Even if you don't understand the point of the class it is still wrong to disregard your education. You should keep attending class and make the most of the situation.
Like why the f*ck is that?
As I said, you need to put a priority on your education. If you don't understand the class, then it's probably even more important to go. That way you can learn the material.
