First night of pre cana...what should I expect?

My Fiance & I attended the Focus class 1st. It was 2 nights. I found that more stressful than pre-cana. The focus class was 157 questions that we had to take sepately, then the next night went back for our scoring. We did great in some areas & not so good in others....like problem solving. I feel all of the major issues come in time with several years of marriage. Overall they gave us some good advice. We already had 2 pre-cana classes & love it. We are learning a lot. We have a big group (7 couples). So, needless to say it has been really great to learn that others are experiencing the same things we are....especially while planning the wedding.
Don't be nervous. Have fun with it!!!!
