Anyone do PreCanna at St Catherines in Franklin Square?

I've made an appointment to meet with one of the priest there to discuss the ceremony, & pre canna.

I'm just wondering if anyone here has done pre canna there (or anywhere maybe). I'm curious to what it entails and how many meetings it is.. how long before the wedding we do it... and just the details of the whole thing....

I really don't know what to expect.
