Remember that you actually have to DO the ritual - not just read it, dream about it or visualize it. Effort requires that you either answer 'yes' or 'no'. Teachers can always tell if someone who comes to them has done the work. But you will also be amazed at how quickly this nervousness will pass as the ritual progresses. Your spirit and inner child.
Nothing stays the same.
To Know you have To Do. Experience requires action. Yes, there will be a test on this. What lies behind us and what lies before us are tiny matters, compared to what lies within us. The rituals and practices follow the seasonal changes of the Earth.
