the school will immediately propose you to take additional practice lesson while u still have yr pre-paid 15 hours. They don't give u a receipt taking yr cash. If u overpay u can never have yr money back. They will just say u something like "u never paid me this money", or "upon my notes u already took all the paid lessons". So if u want anyway to take their lessons be very careful. Note every taken lesson with date and time immediately after lesson in the presence of the guy. Show to the guy that u note EVERYTHING. After every cash payment ask immediately the receipt. And also i can add about timing of practice lessons. They always try to finish a lesson at least 10 min before. Very often the guy is talking too much about his life instead explaining u situations on the road. As a conclusion u can find much better and even much cheaper in the same area (as I did). Read Less
