From A1 to A – Cost question

I’m trying to get through just how much the change from the A1 to the “large A” in Germany costs. The information goes far apart from “about 300 Euro for the rides plus 130 Euro at the examiner and 50 Euro registration fee” (i.e. just under 500 Euro” until “according to driving instructor had to do all driving hours, that was then 10 Normale and the 6 special rides” (16x 50 Euro = 800 Euro only for the rides) I had various finds on the net. their compositions report? Greetings, Martin
