Naviance question

<p>I am trying to figure out my unweighted GPA.
On Naviance it has my "Weighted GPA" as a 4.8 but than under that it has "GPA" as a 4.2..
What does the "GPA" represent because I know an unweighted GPA can't be over 4.0...</p>

<p>It could be over 4.0 if your school gives 4.33 for A+</p>
