<p>Because I want to send my ACT and my SAT subject test scores to colleges, but from what I've heard, sending subject test scores will send all SAT test scores.</p>
<p>College Board (the company that controls the the SAT tests) allows you to excercise score choice and choose which SAT or SAT II scores to send so physically it can be done. The real issue concerns the colleges to which you are applying and a number require you to submit all test scores but what each means by “all scores” varies – some require all SATs and SAT IIs, some require all SATs but you can choose which IIs to send, some require all SAT IIs if you submit any but not the SAT if you rely on the ACT, and there are other variations; you need to check the rules of each college to which you are applying for exactly what is required</p>
