20 credits always too much?

<p>My schedule is filled with 16 credits of required courses and 4 credits of decal/music ensemble courses.</p>

<p>Physics 7B
Math 54
CS 61A
Music R1B</p>

<p>Total: 16 units</p>

<p>Those are all of the classes that I now have on my schedule and won't change. I also would like to add a 2 credit DeCal that I've wanted to take since last semester and a 2 credit wind ensemble class which I feel won't take up much of my time at all, and these take up a total of 6 hours a week, and would bring my total to 20 credits and 29 hours of school a week. Do you think this is too much, or a balanced 20 credits, or what should I do? I thought originally that I would do either the decal or the emsemble class but I can't really decide between the two so I'm kind of weighing my options.</p>

<p>You won’t know until you try… if you consider the DeCal and the wind ensemble courses as “expendable” (i.e. drop them if the overall schedule appears to be too much work/time and they are contributing significantly to the work/time), you can start out with the schedule, then drop one or both if necessary.</p>

<p>You probably know how much work Physics 7B and Math 54 will be (similar to Physics 7A and Math 1B or 53). CS 61A will have programming assignments, so it could be a significant amount of work. Music R1B would involve reading and composition, presumably a bit harder than an R&C A course.</p>
