[English] Study and Learn

For Example：
I am studying English to pass my exam.
I am learning English to speak foreigners.

You can't say learning at university.
You can learn something at university

You should study hard in order to pass your English exam. And you just learn English to speak to foreigners.

Conclusion：
Studying is more detail and thorough than learning.
