For our NM prog, the finale is 'pledge jeapordy' (yea yea yea, we're working on the word pledge

) so that has questions about everything in AST. it is a great review session, plus we require that our actives all go to it, it helps us review for our annual test, plus is good big/lil bonding.
we used to do sleepovers, but people get grumpy sleeping on the floor, (edit- only 10 women live in, so everyone was required to sleep in the living room unless they had a medical reason.) so we changed it to having the nm's plan a sisterhood event. that way they get practice planning, plus we get fresh ideas as the actives aren't allowed to help unless asked. (we don't even really know till right before hand.) the nm educator helps them, to make sure it is line w/ policies, but it works great!
We have pledge class banners too that we hang in our house.
