I got the liscence last Tuesday. The test was not very difficult. Keep good relation with your instructor. Keep him "happy"!!!!. He can arrange for your early test, may be after 12 classes. By the way I enrolled for 30 days course and got the liscence after 12 classes. Also take your ATM or Credit card with you on the test day. If you pass you can have your liscence just after test by paying 250 riyals (for AL-Khebra School, they were not accepting cash ). I hope it will help. And don`t worry. Test is just like "a piece of cake" for somebody who knows driving.
