This basically means youre screwed if this is your undergraduate GPA or grade point average. You probably wont make it into graduate school. Especially if you are a science major. Earning a 2.5 is basically a C+ average and everyone will make fun of you.
Little Johnny attended college earning a 2.5 gpa (grade point average) thinking he was going to be a doctor. He chose a biology major and continued to work his job full time. Subsequently Johnny screwed himself over by earning a GPA of 2.5 in his classes. Johnnny now has a useless biology degree and is $60,000 dollars in debt. Since Johnny cant get into Graduate school he might as well go work at a gas station or contact the local paper for a "paper boy" position. Johnny may know a whole lot about cell biology and human physiology but he will always be seen as a failure.
