It's hard to say. It depends on the time when the driving school arranges to get on the bus and the time when the driving school makes an appointment for the exam. If you learn quickly, you will naturally get the certificate quickly. It usually takes about 3 months to learn a driver's license, and the fastest I have ever seen takes 45 days. Basically, 4 months to 6 months will be delayed by 2 months, and the slowest year is almost the same. If you haven't got a driver's license in the past two years, there is basically no need to learn it, because learning a driver's license begins with passing the theoretical exam. In short, depending on the speed of your study and the quality of your driving school, you can usually get it in 4 months.
