Unsurprisingly, concerned parents are fearful their kids' exam results are under threat because of the amount of time they spend on sites like Facebook.
Two-thirds of mums and dads said they worried about the impact of the web on their kids' grades, whilst almost HALF admit they do not have a clue as to what their youngsters get up to online.
The survey from TalkTalk showed that around 40 per cent of kids listen to music online every day, whilst 50 per cent use Facebook, Twitter or MySpace.
However, 76 per cent of the parents polled admitted they SHOULD be taking responsibility for what their kids do online.

Or is computer usage a bit of a free for all in your home?
