Math major?

<p>I'm starting to stress a little about applying as a math major. I real do not perform well on standardized tests and only got a 690 on the Math II subject test. I fear this won't make me competitive enough to get into UCLA or UCI with that score. Would it hurt my admission chances if I applied as a math major? It's really the only thing I've wanted to major since I was a 7th grader</p>
