Ways You Can Take To Increase Your GPA From 2.5 To 3.5

I hate to break it to you, but...

3.5 x 8 semesters = 28
2.5 x 3 semesters = 7.5

In your next 5 semesters, you need a 20.5 / 5 = 4.25 GPA (or to take more classes to more heavily weight your last semesters, or to stay more than 4 years, etc.).

You're going to have to go from below average to almost perfect to obtain a 3.5 GPA, and make that change overnight. Realize that, and kick yourself into gear right now, or you're going to be too late to accomplish your goal.

It may be  pretty difficult to raise your GPA above 3.5 and you need to take heavier class next semester to increase your GPA above 3.5.

Or another possible solution: If it is possible take the classes with low scores again, take them again. It will drastically increase your GPA. Besides, even if your GPA for next semesters will be high, lower scores on early semesters will be noticed by admission office. If you take that classes and increase your score, admission office would be more comfortable about accepting you.
