Junior Year vs Cumulative

Ok, so my cumulative of all years for HS was 3.78 including the first semester of senior year because freshman was 3.6, sophomore was 3.67, junior was 4.06 (4.17 weighted) and senior was 4.0 unweighted. My junior year was my best year and there was improvement throughout the years, but my cumulative is low bec

So is there a question here?

You need to recalculate your uwGPA with a 4.00 max scale (is no grade give you more than 4, so your junior GPA cannot be 4.06). Otherwise, you are overestimating your GPA.

An A+ might be more than 4.0.
