The program supports variable credit hours per course and uses a standard GPA conversion scale.
- Accepts either numeric or letter grades for each course.
- Supports custom credit hours per course.
- Automatically converts grades to GPA points using a defined scale.
- Handles invalid inputs gracefully.
- Displays the final GPA rounded to two decimal places.
