Collect Study Material
Some students over estimate themselves and start collecting all the books and study material available on this planet to prepare for their exams, only ending up confused and panicked. They fail to understand that they aren't superheroes who can mug up everything in just one day.
Students try to get in touch with friends whom they do not even talk very often, asking how much of the portion they are done with. Sometimes, this acts as a boost, if they are ahead of their friends. But God forbid, if they hear that their friend is revising the syllabus, then, BOOM! Panic starts, followed by regret.
Students start taking breaks in between their studies. Mind you, those breaks are mostly after 15 minutes of studying. And then, once the break starts, it only ends after they have watched two-three TV series. Suddenly, realization dawns, and they get back to their studies, only to come out again after 15 minutes.
Now they ponder upon how they could have studied earlier and avoided all the exam panic they are going through. How they should have focused on studying rather than hanging out with friends. And then they decide, from the next semester, they will definitely start studying beforehand, which obviously doesn't happen either.
