My friend
As long as u r batular, yeh it is possible to save + 3500 QR per month. As per ur offer It seems u have to arrange every thing of ur own. Make sure u have to live in a shared accomodation which will cost u at least QR 1000 to QR 1500 pm + another QR 1000 (Max) on food items including other activities which will include internet, telephone and so on. GOod luck.
