what is the difference between unweighted and weighted gpa
Unweighted GPA   The unweighted GPA is the average of all class grades based on a 4.0 scale. If the student earned an A in an advanced English class, the unweighted grade would still be a 4.0- the corresponding number on standard grade conversion charts-instead of, for example, a 4.5.
First, weighted GPAs are used for weighted classes. These classes are the honor-type, higher-level classes (also assumed to be more difficult) having bigger worth than your regular class subjects (unweighted classes).
