hi,
A full-time MBA program does require massive commitment to academic load and out-of-class activities. i am definitely quiting my [post-undergrad] job when i start my MBA. as a matter of fact i am quitting my current job just so i can better prepare for the GMAT. i haven't decieded yet, but given the fact that i hate my job so much and everything around it, i think it will be a good idea to quit and study as hard as i can. on the other hand, $$$ will be tight, but hey no one said this journey will be short and trouble-free. there will be some obstacles down the road. work sux i'd rather be in school all my life, those are my 2 cents.
