I check the SAT policy of Cornell:
“Cornell University requires freshman applicants to submit either the SAT or all ACT scores. Cornell participates in the College Board Score Choice program. For the SAT, Cornell considers the highest section scores across test dates. For the ACT, Cornell considers the highest composite score across all ACT test dates. As a reminder, ACT does not create new records by combining scores from different test dates. In addition, each undergraduate college/school at Cornell has specific requirements for SAT Subject Tests (see requirements below).”
If I have taken three SAT tests, and the last one is the best one. Can I only report the best one score and sent the ONE official record.
Yes, you can provide whichever SAT tests you choose to report. Be aware, however, that preventing College Board from providing the other SAT tests, does not necessarily mean Cornell will not learn of those scores. You need to check what your high school does to determine the issue, because many put all your scores on the official high school transcript sent to colleges. and thus, if yours does so, withholding the scores via College Board will accomplish nothing.
^Cornell, starting last year, dropped its “all scores” requirement for any SAT or SAT subject tests, and thus one can now choose which SAT or subject test scores to send, but, inexplicably, it kept its “all scores” rule for ACT scores. There are only four other colleges still left that have an “all scores” requirement: Georgetown (for all SAT, ACTs and subjects tests), Yale (for all SATs or ACTs, or all of both if you decide to send both, but score choice accepted for subject tests), Carnegie Mellon (same as Yale), and Barnard (for either all SATs or all ACTs, but not for subject tests because they are not considered for admission),
