That’s wonderful. So glad you are beginning your RCIA journey.
But keep in mind, RCIA is not a course.
RCIA stands for the Rite of Christian Initiation for Adults-- it is a series of rites in the Church during the stages of the catechumenate (for unbaptized) or through the various stages towards confirmation and full communion for the already baptized.
The catechumenate is ordered towards leading catechumens and candidates into living a Catholic life through liturgy, prayer, worship, and the sacramental life. There are also pastoral dimensions fulfilled by the pastor/clergy, lay ministers, sponsors, catechists, and others.
Catechesis (which may take the form of classes) is one part of RCIA, but it is not RCIA.
