Should I send this SAT Subject Test score to the UCs?

Hi everyone,

I took the December Physics Subject Test and received a pretty low score: 660. Unfortunately, this is pretty bad news because:

  1. I'm a senior so I don't have time to retake the test
  2. I said on my UC app that I was going to take the test in the future, so they'll know what's up if I don't send it
  3. Unfortunately, this test is recommended as I'm majoring in mechanical engineering

So, now I’m not sure what to do. Would it be worse to send the score or to not send it, considering the three facts above and my score? Will the 4 I received on the AP Physics 1 exam and the As I got in AP Physics 1 help me out? Thank you for your input!
