UW
Some colleges recalculate their own unweighted and/or weighted GPAs for all applicants.
Some colleges holistically look at academic records.
Some colleges take GPAs from transcripts at face value (for example, https://scholarships.ua.edu/faq/ ). At these colleges, attending a high school with exaggerated weightings for weighted GPA is advantageous.
For discussions on these forums, weighted GPA alone without any description of the weighting system conveys insufficient information about how well the student did in high school. A 4.5 weighted GPA may have come from a 4.0, 3.5, or 3.0 unweighted GPA, depending on the high school’s weighting system.
