unfortunately rezymalik, there is only Qatar University that offers MBA in Qatar. i believe there is an option to study full time or part time, and yes, by saying part time means afternoon or evening classes.

there is also the Institute of Professional Managers here in Qatar that offers a mini-MBA (whatever that means!). you can google it for their contact details. the site is in arabic, i think.

good luck. as for me, i'm going to continue looking for a good online university. i'm not a structured learner.
