Figure out what your GPA is so you know where to start and how long it will take to raise your GPA. For example, if you have a 2.5 GPA and want to raise it to a 3.0 or above, you have to figure out how many classes to take, what the minimum grades you can receive are and how long it will take to raise your GPA.
Work to reach your desired GPA by studying and handing in all of your assignments on time, done correctly and double checked for mistakes, misspellings and other errors that will negatively affect your grade.
Calculate your GPA regularly to see where you stand. For example, you have a 2.5 after your first semester in college and you took four classes. To raise your cumulative GPA to a 3.0 in one semester you have to take a minimum of four classes and earn at least two "A"s and two "B"s. You can calculate this by using the GPA conversion, which provides numerical value to letter grades.
A = 4 points
B = 3 points
C = 2 points
D = 1 point
Give each of your grades a numerical value, add the numerical values and divide them by the number of classes you are taking. For example, you take four classes your second semester and earn two "A"s and two "B"s. That gives you 14 numerical points, which you will divide by your four classes to come up with a GPA of 3.5. To see if your cumulative GPA is at your desired goal you have to add your grades from both semesters and divide them by the total number of classes taken.
