Wait. We learned this!!!!???

I am Harry
Harry is me

I think you have Ron and Harry mixed up. :p

Mostly I'm Hermione, until the last three questions. Then I'm Harry.

I don't know if you are referring to high school exams or college exams, but in my experience high school exams were easy for me like real easy, as for college i can't say because i have not attended college yet

In some subjects I'm Hermione, in some Harry. There is no inbetween, I'm literally never Ron. I either know it or am lost.

I'm Harry all the way
