From C152/C172 to C210

[PPL152]

Hello,
I have been flying C152s and 172s, logging up around 120 flying hours, and wish to start flying a C210 at a flying school. From your expeirence, do you think 1 good checkout will do to fly it on my own or do you think you would need a couple of flying hours on it before going solo?

Thanks for your input guys
