I can only recommend this driving school, I struggled with the theory test, after a week of intensive on-site learning and more detailed discussion of my mistakes, I passed with 0 error points. Everything was great with the driving instructor. No trouble nothing. And if you are upset about the prices you don't have to go there :) there are far cheaper driving schools in suhl but are they just as good? And that you can't just postpone your open bill as long as you like, you have to be clear because fuel, insurance, etc. also want to be paid somehow.
