Importance of SAT Math II

I’m a senior next year and I took AP Calc BC last year and got a 5 on the test. I also recently took the SAT Math II and got a 700 on it. Which, for me, is really bad, considering I’m aiming for UCLA and/or UCB. My UC GPA is 4.45 and my ACT is 33. Plus a lot of extra circulars and and AP’s, also I’m taking Physics C next year. The problem is that I’m aiming for Aerospace engineering as my major, and at these schools, you have to be as competitive as possible. Is SAT Math II really necessary any more or will my other academic scores cover it?
