How far in advance should I register for the theory test?
I'm pretty far along in my learning, but I still need some theory lessons. Due to my age, I can't take the theory test until April 1, 2023, at the earliest.
How far in advance do TÜV Süd make appointments, and how long do I have to wait for an appointment?
Apparently it depends on the utilisation there, from just under a week to many weeks.
What does your instructor say?
