What are the Effects of Korean artist or singers in the academic performance of a student?

Hi there...Relating to your question above, I think that there are several effects towards students' academic performance.

1. Wasting time in browsing the news of their favorite Korean artists. Example: facebook, blog, twitter and etc.

2. Can't concentrate while doing their revision.

3. Using hand phone to view the Korean artists' music and news during class.

Hope that I can answer your question.
