Why is my Cumulative GPA different from my Weighted GPA after One Semester?

I completed my first semester of high school last month. My stats are…

UNWEIGHTED: 4.00
WEIGHTED: 4.17
CUMULATIVE: 4.13

After one semester, how is my weighted gpa different from my cumulative?

Thanks

This is a school specific question; ask your GC. When you find out, tell us, because I have no idea why that would be the case.

Did you take any classes last year that counted as high school credit? Maybe your school factors them into you’re GPA somehow.
