Hmmm based on my experience, I enrolled half course just to familiarise the crazy round abouts of Doha. Since I have my driving license back home  I was approved for 25 days. Unfortunately I was assigned to one instructor no need to mention his nationality whom could not speak English well. I felt pitty for them coz he told me that If I will help him he will help me also which means every end of the day you have to give him some extra extra hmmmm ... which id bribery for  the students  especially ladies. If you passed another extra extra . If you failed you have to give more extra . I asked one friend she said they are doing this since the Driving schools don't pay them that much. I don't understand as well. Cost of driving lessons is QAR 2000 for full course and during that time the instructor was getting QAR 600 p.m. . So if you want the instructor to teach you very well you have to give them extra extra
