You can have additional driving lessons (not to confuse with the course) if one of these conditions is fulfilled:
you have finished a course in GAZeLka school
you have finished a full course in another school in Poland and you are preparing for the exam
you already have a Polish driving licence.
you have your valid driving licence (from a country, whose licences are acknowledged in Poland) and you are not currently converting it*
*That means that if you have already started a process of converting your driving licence (you have received your PKK but you still haven’t passed the theory exam), you need to wait until you pass it and then you are welcome to come and drive with our instructors.
