I am currently doing my MBA at Universiti Tun Abdul Razak. The total tuition fees is about RM17k- 18k. The duration of the course depends on how many subjects you take per semester. If you take on average 3 subjects for long semester (4 mths) and 2 subjects for short semester (2 mths), you would be able to finish in 2 years' time.

Classes are held on weekends, and sometimes, you will have to attend online classes, depending on the lecturers. The programme is supposed to incorporate online learning and face to face learning. As usual, some lecturers are good, and some lecturers are just "so-so".

Yeap... It's an MBA from UNITAR

I am not sure how many years of working experience you have. If you have substantial working experience, more than 3-5 years, it might be worth considering to resign and pursue your MBA. But if your working experience is only 1-2 years, you resign and get an MBA, your MBA will not be very valuable because of your lack of working experience. If you have just worked on and studied part time, you would have added on your working experience.

I have heard of MBA graduate without much working experience who is nothing but mere theory expert who cannot apply what he learnt to his working life.

You decide whether you should resign or not. If you are comfortable with the working experience that you have, and you have the money to support yourself through the MBA, then you might want to consider resigning. But in my view, if you are able complete your MBA part time, you have just proven yourself to your employer that you are able to cope with stress and heavy workload.
