Re: #28
UCs by policy emphasize GPA and deemphasize test scores. The result is that any test score based selectivity ranking will underrate them, while a high school record based ranking will overrate them (note UCLA versus USC in each version). This emphasis also can give unpleasant surprises to test score heavy applicants that fall a bit short on GPA.
Note that UCs do not use rank from the high school, but probably use ELC recalculated rank for reporting these stats.
