Thanks a lot mate..
Yar I personally know not of even a single reason why you should not do OBU Thesis
It's not that difficult, just get a good mentor and you'll be fine. If you can afford it then do it.
Regarding the degree, every employer has their own requirement. Usually it is Upper Second or above, but sometimes merely a degree suffices.
You dont have to commit your years to it, it's just a thesis, adding 3 years to your formal education.
Han e to hai yar ke it doesnt have much value in Pakistan as of now (most unfortunately), lekin you told once that you plan to move abroad. It's value differs from culture to culture, but generally, the situation is better everywhere than that of Pak.
So i'd recommend you to do it, you can always do B.com, M.com, or any other masters that you plan, it will only make your CV better.
