When I teach, I seldom talk about the Catechism, too.
But, I am always teaching from it, even though it’s my hand-written notes that I copied out of it, most of the time, rather than reading from the book itself.
Maybe it’s the same with your Catechist.
But I’m very sorry to hear that they are still treating you as a Catechumen. I will pray for the Holy Spirit to make up for the lack, and to ensure that you receive your proper training from Him, if you can’t get it in your class.
And do follow the Rule of St. Benedict, with regard to obedience even in the face of contradiction, opposition, and unreasonableness. You will need the practice for when you actually become Catholic, since we Catholics abound in contradiction, opposition, and unreasonableness - the more practice you get in this, early on, the better prepared you will be, for the reality of the Church.
