I want to learn driving. Can anyone help me in this regard?
the only way to learn driving is to go to a driving class "Fahrschule". Those are located in nearly every corner in German cities.
You have to do a theoretical and a practical driving test. For the theoretical test you'll need 14 units where you take classes and learn the subject. Parallel to this you do the practical driving, there you will need at least 12 driving lessons.
Do you have any specific questions about attending the courses?
Maybe this will help you a little bit more:
If you are applying for a job, where a driving licence is required, there is the possibilty to ask for financial help at the Arbeitsagentur... But without a very good reason the chance is slightly small to receive such help.
Unfortunately, it is (very) expensive in Germany to make a driving licence... Can I ask why you need it?
