Math grad program

I want to apply to grad program for applied math. Anyone knows How competitive is it to get to schools like uci, ucsd, or ucr? I actually dont care what school but the one that offers me the most financial aid. Im in my third year at ucla, i am going to take the general gre this August, and maybe the math gre next summer (should i take it though?). Any advice about math grad program at these schools?

I meant to say I am going to be in my third year this fall 17.
