Due to the way this calculator is made, it won’t calculate grade replacement if you are repeating a course. GPA Calculator will include both failing and new grades.

First, you need to enter your total grade points. Take a look at the table below and calculate number of grade points you earned so far. For example, if you have taken only one term and passed 6 courses with grade B, your total grade points would be 18 (6 courses x 3.0 points).

A smaller number in front of a larger number means subtraction, all else means addition. For example, IV means 4, VI means 6.You would not put more than one smaller number in front of a larger number to subtract. For example, IIV would not mean 3.

You must separate ones, tens, hundreds, and thousands as separate items. That means that 99 is XCIX, 90 + 9, but never should be written as IC. Similarly, 999 cannot be IM and 1999 cannot be MIM.
