English problem.

 Why I feel don't want to study?
I felt different.

why in high school, I really love to study.
but when I enter university, the spirit to study has gone. 
I don't understand what lecturer teach in the class.

After 2 years, I start to recognise that maybe my issues with English is the reason. 

Honestly, I have very bad English although I have entered University for two years.
Learning in English, presentation in English, even my roommate is a Champion in English Debater. 

Is it my English or myself that block my mood to study?
