thanks Dusan..
well I'm torn between power engineering (which requires thermodynamics

.. ) and communication engineering .. and it's about time to decide cause in October I will start into one those too .. I've studied the situation well ..
As a Saudi, a country that depends almost 100% on oil, I know that oil is bound to cease powering the world and, needless to say, we have the sun almost 365 days a year.. I think we should work alternative energy more than other.
In the other hand, communication is just what I enjoy studying. Market is big but underdeveloped here in Saudi so I can do some pioneering in it. I'll see what the professionals say around here.
