Will Math 53 or CS 61A be full?

<p>I have a problem here: I will definitely need Math 53 and CS 61A for my first semester as an EECS major, but since they are still far from full (259/475 for Math 53 and 162/370 for CS 61A), I'm considering getting them in Phase II which begins on July 17. Are they likely to be full by my appointment time (July 27)? Any advice is appreciated!!</p>
