Policies on SAT Subject Test scores

Hi. I am curious about the various policies surrounding submitting scores for SAT Subject Tests. I am a high school junior and I took three subject tests last spring for practice prior to my AP exams. I did fair, but not stellar for some of the schools that I plan to apply to. I plan to take several this spring after intense preparation. Are there any colleges that require all of my SAT Subject Test scores, or can I always choose which, if any, to send? I am concerned about the following schools:
-Duke
-Northwestern
-Georgetown
-Richmond
-Notre Dame
-NYU
-UChicago
-Michigan
-GWU

Thanks!!
