Should I cancel my SATII tests?

I took the May 6th tests and the third test I took, I didn’t even prepare for and took it as a “practice”. I came to realize that some schools, like Cornell and UPenn, require full testing history, including subject tests and now I’m wondering if I should cancel my entire test day or keep it. Is there a full list of schools that require all SATIIs? Is it worth cancelling everything for those few?

For a list and discussion of schools that require all scores, go here: http://talk.collegeconfidential.com/sat-act-tests-test-preparation/1912440-must-you-submit-all-sat-act-or-sat-subject-test-scores-p1.html. Upenn now allows you to send whatever tests you want to send as it dropped its all scores rule last year. Also, the only colleges that currently require you to provide all subject test scores are Cornell, Carnegie Mellon, Georgetown, and Harvey Mudd. If applying to Georgetown that third test is needed because Georgetown highly recommends three subject tests not just two. Cornell, Carnegie Mellon, and Harvey Mudd use the highest two for determining admission if you send more than two.

for SAT 2s, you can pick which scores you want to send, ask your guidance counselor but I thought you could select which scores to send.
