Everyone I know has already gotten secondaries. I think they send it to everyone. It's just a matter of time (they are very slow). It's their way of making easy money (most schools do that).
I don't think UCLA will reject anyone this early. I think they wait until the last minute (in May or whatever) and send you a letter stating that the class is full.
But, I know if you get an interview there either you are gonna get accepted or waitlisted. They don't give out many interviews.
