dear han19,
I didn't find grocery price list here but got the link to get one, in Iloveqatar.

What do you mean to get sharing accomodation, will you please explain ?

how can a bike be more expensive than a car ?!!! I gotta have a 125cc yamaha bike here, its far less expensive than even a reconditioned car.
anyway, how about the bus costs ?

I visited Qatar University website, the cost as I got, is almost 1500-1750 QR. Its high but maybe I can manage.
Is it really tough to get admitted there ?
is there competition for the admission ?
how distant learning is possible ?
