If you are not in a hurry to get driver's license, go to Al Khebra, the shortest course is 12 days for 1,210. At Karwa, you'll pay the same (maybe more expensive) but the course is for 7 days only. I had my driving lessons at Al Khebra, I passed the first time. But now I think it's much easier to pass because they have replaced the box parking test with straight/diagonal parking. Best of luck.
