The Spring and Autumn Seminars are traditionally split into the intensive seminar on Saturday and the Kyu Passage seminar on Sunday. The Sunday seminar is not only a Passage seminar - in between the subsequent passages (Kyu tests) the teaching will follow the topics of the intensive seminar before.
So, it makes sense to attend both seminars, but you may book them separately and join only one day as well.
