Some first-year applicants to Cornell take college or university courses during high school, sometimes called "dual enrollment." 

If you complete college or university coursework through a "University in High School" program and this coursework fulfills a requirement for high school graduation, there is no need to request that the college or university you attended submit a transcript to Cornell as part of the application process. In this case, the college credits will not transfer as Cornell credits.

If you complete college or university coursework that does not appear on your high school transcript and does not fulfill a requirement for high school graduation, your college or university transcript should be submitted to Cornell in addition to your high school transcript as part of the application process. In this case, the credit(s) you received may be eligible for Cornell credit. You should request that the college or university you attended submit your official transcript to Cornell. The Cornell undergraduate college or school you apply to will determine whether the credit(s) will be transferred.
