But, what's in general different: The clearance is covered by the insurance every student has to have around here (about 2000 $ / year!). You can book an appointment online and get an e-mail and a text message reminder a day / an hour before your appointment starts. That's very useful because an missed appointment will cost you about 50$.
Once you've arrived on time, you check in 15 minutes early and you wait for this very exact time until you're called into a room, any examination or whatever is done, and you usually don't need the time your appointment is supposed to last (e.g. today I was done after 10 out of 15 minutes). In Germany I experienced a waiting time of up to an hour or even longer, even if I had a scheduled appointment..."German efficiency" ;-)
