The only thing I can recommend is to speak to your priest. It could be that the curriculum is focusing on the new testament now and will cycle to the old testament later - when I was a child, our curriculum worked as I just described. Or it could be that the church/diocese itself is shifting focus. Your priest can explain to you whats going on so that you can make an informed decision.
