Letter grades are each assigned a point value:
4 = A, 3.7 = A-, 3.3 = B+, 3 = B, 2.7 = B-, 2.3 = C+, 2 = C, 1.7 = C-,
1.3 = D+, 1 = D, .7 = D-, 0= F.
To calculate your grade point average, first multiply the number of credits each class is worth by the point value for the letter grade that you earned in that class. Next, total the grade points of all of your classes for that semester and divide it by the number of credit hours that you attempted. This is your semester GPA.
Example: class
MATH 107
grade credits grade points
B+ =3.3 points X 3 credits = 9.9 grade pts
ENGL 101
COMM 101
ART 100
PE
C =2 points X 3 credits = 6 grade pts
A- =3.7 points X 2 credits = 7.4 grade pts
A =4 points X 3 credits = 12 grade pts
A = 4 points X 1 credit
GPA = total grade points (39.3) divided by the total credits (12)
= 4 grade pts.
12 total credits 39.3 grade pts
GPA = 3.275 = 3.28
Your accumulative GPA is calculated in the same way except that your entire college record is calculated instead of just one semester.
Your accumulative GPA is calculated at the end of every semester. If it falls below the *minimum
GPA, you will be placed on scholastic probation. If you are on scholastic probation and do not earn at least a 2.00 GPA for your next semester of attendance, you will be dismissed.
The *minimum GPA is as follows for the : total credits attempted minimum ISU including transfer credits accumulative GPA
0-25 (freshmen)
26 on up 2.00 (sophomores, juniors, seniors)
The satisfactory progress minimum GPA guidelines for financial aid are the same as for scholastic probation.

HOW TO FIGURE WHAT GRADES YOU
NEED TO ATTAIN A CERTAIN GPA
If a student has a 1.50 semester hour GPA, has earned 12 hours, has 18 grade points, is enrolled in 12 semester hours and wants to have a 2.0 accumulative GPA at the end of the current term. Here is the process:
1. Add up the total number of ATTEMPTED hours the student will have at the end of the semester that must be calculated in the GPA (in this case it will be 24 semester hours).
2. Multiply the number of hours by the cumulative GPA the student wants to have at the end of the term (in this case 24 sem. hrs. X 2.0 GPA = 48 grade points)
3. Subtract the number of grade points earned (18) from those needed to achieve the desired GPA (48). The equation in this case is 48 grade points - 18 = 30 grade points.
4. The next step is to divide the number of grade points the student must earn to achieve the desired GPA (30) by the number of semester hours in which the student is currently enrolled
(12). In this case, the equation is 30 grade points divided by 12 semester hours = 2.5. The student must earn a 2.5 in the current semester to have a 2.00 at the end of the term.
5. The final step is to determine if the grades the student is currently earning or typically earns and the GPA he/she desires are compatible and realistic.
