Hello Mark,
That is really not for me to judge! Life is full of choices and often these should be based on priorities (wow, I am getting philosophical :-)).
If 16 March is also a CAS member night there will be two clashes with our first course, out of seven course nights. If you are interested in our courses it might be an idea to not skip the first course night as there will be a lot of introduction happening.
But it really is your call. Maybe also find out what is going to happen at the CAS nights?
Cheers,
Erik
