The fall is rapidly approaching and there's still time to enroll in some business courses. Most courses start in early September, so time is short. I had been thinking about enrolling this fall, but I plan to wait until spring. There are simply too many things going on in my life this fall.
If you're considering a part-time MBA, you may want to think about enrolling in a single course prior to matriculation. Some business schools will allow you to "test the waters" and take 1 or 2 courses as a non-degree student. If you choose to enroll, then those credits would transfer into your degree program.
