I enrolled in Gulf Driving School some time in December. Its a long wait to get the timings best suited to you. Its best to get them done in one stretch, perhaps when you have some training rostered.
As for paying and passing, it honestly does not work. You can pay as little as QR50 to get some extra attention from your instructor but it only increases their appetite. It really depends how you want to go about it.
I heard they are becoming more strict with women drivers and also trying to curb the number of cars on the road.
Don't forget your knowledge of traffic/road signs are just as important as the L, pocket-parking and road test. Best of Luck and Drive safely!
