Too many credits?

Hey guys I’m taking summer classes (15 credits worth) and holding down two jobs. Does this seems like it could be too much? I’ve only just started the quarter.

Does this summer quarter have as many weeks as the fall quarter will, or is it shorter. If it is shorter, you are taking way too many classes.

Even if it is a regular length of time, this is too many classes because you are also holding down two jobs. With your work schedule, one class is probably plenty.
