Students ask why they should take the SAT subject tests? I tell them it adds to your application file, showing proficiency in a subject. The majority of schools do not require them, but will consider them, if sent. If they are majoring in engineering, the sciences or pre-med, then colleges will want to see two subject tests, usually math II and one of the sciences test. If you have scored well, then go ahead and send the scores to the colleges you are applying to.
