What is the Grade Point Average for a Cumulative Weighted of 72.33?

There's no single answer to this question. A cumulative weighted average (72.33 in this case) doesn't directly translate to a GPA. The GPA calculation depends on:

* The grading scale: Is an A a 4.0, a 4.3, or something else?

* Credit hours/weights: Were all courses weighted equally? Some courses might be worth more credit hours than others.

To convert a cumulative weighted average to a GPA, you need the information about the grading scale and the credit hours for each course contributing to that 72.33 average.
