|Be different; leave social networking for a week!|
If you're starting your final exams then it might be a smart move to deactivate social networking sites. I know you can deactivate Facebook, not sure if Twitter and others have the same tool, but I am sure you can find a way to stop using them during finals. Believe me, you'll find so much more time to study and finish up papers and other assignments; you won't be checking what everyone is doing every five minutes! Turn everything off for a week and use the extra time productively.
FYI: I permanently deactivated Facebook. That's it; I am done with it. I have much more time on my hand now than I had when Facebook was active.
