How to get rid from academic stress?

I am sitting on my couch. I see my younger brother is depressed .I asked him what happened ? He replies me when ever I did my exam from Internet I got less mark but when my friends did their assignment from the internet they got more marks then I suggest him to first read the reviews from assignment service .If the website have positive reviews than fetch data from it for your assignment .After reading from assignment service he find big websites reviews like Real Assignments Reviews and get more marks in assignment from his friend .Now he is roaming freely.
