That does sound strange. I had 10 (hour-long) lessons, and had covered all of the manoeuvres in that time. I had a few (2 or 3) 2-hour lessons after that, going over the manoeuvres and a few other things in the week before the test, but that was it. It sounds strange not to have started yet.
Have you asked your instructor about it, told him you want to do more?
