RMIT University converts every graded course into quality points by multiplying the grade's point value by the course's credit hours. Your semester GPA is the total quality points divided by the total credit hours that count toward the GPA, and the result is rounded to the nearest 1 decimal place. Points run from 0.0 up to 4.0, so a higher average is a better result. The scale has no plus/minus steps, so every grade in a band is worth exactly the same number of points.
What gets left out of the average
PX, DEF, NEX, WDR, CA, NC, EX, and RNY carry no point value at RMIT University, so a course marked with one of them drops out of the division entirely โ it changes neither the top nor the bottom of the fraction. PX, CA, EX, and RNY still earn credit toward your degree while staying out of the GPA, which is why your credit total can climb in a semester where your GPA barely moves. NN, NH, DNS, and NYC work the other way: they earn no credit but are still counted in the average at 0.0 points, so a failed course pulls the average down while adding nothing to your progress.
How this semester rolls into your CGPA
RMIT multiplies credit points or contact hours by grade point value, divides by total credit points/contact hours, and rounds GPA to one decimal point. In practice that means your existing CGPA is turned back into quality points by multiplying it by your completed credits, this semester's quality points are added on, and the total is divided by your new credit total. Both the semester and the cumulative figures are rounded to the nearest 1 decimal place. Repeat handling is not published as a rule this calculator can apply automatically, so retaken courses need to be checked against the current catalog.
