BUS-Z302 and X204 ?

<p>I'm planning to take Keith Dayton's Z302 in the second 6-week. and J. Heidwald's X204 in the third 4-week. Both of the two courses end on July 27.
I'm wondering whether I drop Z302 or not because I heard there was also a case competition in Z302. I'm afraid there will be too much work if I work on two cases at the same time. But I cannot decide now because I don't know how Z302 works.
If anyone can give some suggestions on my question or information about the course structure of Z302, I'll be very grateful :)</p>
