It’s true that high ranking CS college graduates have higher starting salary. Check GA Tech’s data: https://webapps.gatech.edu/cfcampus/adors/commencement/salary_report_result.cfm?termcode=201708&college=TOTAL&level=1&surveyid=105&Submit=Submit
I doubt unknown college CS graduates can have average starting salary over $95k. There’re always exceptions but “It’s the exception, not the norm”.
