I did some lessons with an instructor whose car I found really uncomfortable plus he only ever had me driving in a certain area never practiced the route at downsview. I ended up failing my first try at downsview. My licence is expiring and I have a shot at doing it again in 10 days at port union. Does it make sense to book at port union (downsview isn't available for another month) and does it make sense to change instructors at this point?
