Don't go work. The starting pay is sh*t and it doesn't provide enough exposure.

I would say if you study SIM, chances are it will be quite hard to get accepted into the Big 4 audit firms. If you have the money, go overseas to study. If not, you may want to try your luck and appeal your way through local uni. Your last option will be to go to SIM and work your ass off (ie. do alot of internships to boost your resume).

Good luck!
