I cannot get good marks

Hi, im a student at pharmacy education. Currently in my 2nd year. My marks unfortunately not good in the 1st year both term. Especially the 2nd term, as it was really bad. That makes my current taken study in 2nd year really small. The problem is that,because of internet. I cannot let go of my internet. What should i do to it. Should i cancel internet for a long time? So that i can study more, or i go to dorm where there is no internet, and back every saturday so that i can get good marks?

i think you cant just take and refuse from internet you can do it bit by bit or you can use internet for educational purpose,or use it when you have a spare time im sure that you can
