Not nearly as good as Hunter. Compare the accolades and college admissions numbers for each and Stuy comes up short. Hunter College High School comes up less often in discussions of competitive NYC schools because the student population is relatively small and because it is not administered by the New York City Department of Education (the primary enablers of the crack cocaine epidemic). Give the place a good once over and you'll think twice about sending your kids there.
Jamal wasn't excepted to Hunter in the 7th grade so he took a shot at Stuyvesant two years later and did just fine.
