Will not sending SAT II's harm me?

<p>So, I just took the Math II and Literature subject tests today. I think I may have done alright on Math II, but Literature was just terrible. Most of the colleges I'm applying to don't absolutely require the subject tests, but instead say that they are 'recommended'. If I end up not doing well on these tests, will it harm me in admissions not to send subject test scores?</p>
