Hi, I would suggest you to start reading and speaking in English everyday. Think in English and speak in english. Read as much as you can and watch english movies in your free time.

And do not expect a change in your comprehension suddenly, it takes months to develop fluency and understanding.
P.S. - I am also a student but I thought I should share my experience with you. Hope it helps.
