Jamilriga. I think it's fair considering that your accomodation is free.  Transpo and free ticket every year not bad. For food you can save if you share together with fellow noypi. If you'll be on your own 600 to 800 riyals monthly you have to spend on food. Everything is expensive considering most of the food items are imported. By the way my friend who is a civil engineer and a manager of the project is getting 12000 riyals as basic pay, free ticket, insurance, transpo plus his house rent allowance is 6000 riyals. But he got 26 years gulf experience in his sleeves. You'll get more as your experience goes up.
