With some exceptions you do not have to report all scores.
Check the admissions requirements for each of the colleges to which you're planning to apply. A small number (perhaps none to which you're applying) require all scores, SAT reasoning and SAT Subject Tests. An example of such a college is Georgetown. A small number require all SAT reasoning tests, but allow you to score choice for the SAT Subject tests. An example of such a college is Stanford. The majority of colleges allow you to score choice for both SAT reasoning and SAT subject tests.
What is score choice you ask?
When you submit scores (online through the College Board site) you will be asked which scores to send. Pick them from your list of available tests. It's straightforward.
