Can I go to grad school while working as an internal auditor?

I did it and only had a problem once: the professor scheduled the final on a day I was going to be out of town and would NOT make any other arrangement for me when I explained the circumstance. This was in a Fully Employed MBA program too so the expectation was that all the students are working as well. I ended up flying back the evening of the final and racing to school in time to get to class late. In retrospect it would probably be a good idea to talk to your professors at the beginning of the semester to find out how flexible they can be in the event you have to miss.

It depends on (a) the job, and (b) the course. Does your boss / HR Dept approve of your classwork? If so, maybe your boss can work your assigned travel around those nights when you HAVE to go to school. Some instructors / colleges make appropriate allowances for students who have to miss some classes (evening / weekend students, especially in business, bring in lots of revenue). IMHO, 9 credits is too much, cut it back to 6 credits.

(Controller). You can try on-line classes too. I've done the last two years on line and was able to work and travel with no problems. I've had classes with students from Japan, France, Indonesia and Germany. I personally did the University of Phoenix and have loved the experience.

Depends on how much pain you can endure. With the travel, an on-line program might be a good fit. I did an MPA program 7 years ago, traditional style program. Took 3 years, taking one course a semester (fall, spring, summer), ocassionally taking two courses at once. Working a full-time job (CFO), all I did was work, study, and sleep. I remember sitting on the sidlines of numerous soccer fields, working through accounting problems or reviewing my study cards. Followed that with 12 months of preparation for, and passing the CPA exam.

Good luck with your endeavor. Stay persistent.

Other than the travel, do you have a "normal" 8 hour day? I just finished an MBA from a top program several years ago. Worked fulltime and took night classes. Usually one class was enough. I took two classes some semesters and that was tough. I think three is too much if the program is at all rigorous.
