Since the driving here is left hand side, as opposite of what is in India, it is advisible to join a school for short course(15 days) before taking a test. You have to pay QR 1400. but you will get only two chances. Other options are to go for half course for about 2400 or full course at 2600(you will get 4 chances). It is better to go to a driving school near to your residence. They will guide you.
All the best.
