Parents need to make sure that their kids are not spending too much on the internet or watching T.V around exam/test-dates(Take the fuse out of the stabilizer or disconnect the modem); .Children who do not use internet at all ; suffer socially, and have difficulty working with study groups. So, no T.V or internet at all, is not the answer.These days most persons are misusing the internet instead of using it productively;
they waste time on porn and social networking sites.
Students are falling academically because they are addicted to rubbish on the world wide web.
I know a girl who failed in her 12th (grade/yr?) exam because of her unfaltering chatting habit.
