thats a shame, where i trained, Novice covered signs 1 - 40 (i think?), each hour long class did have a short (10 or less) sign course at the end, but it was the signs we already had been taught. the majority of the class was the signs being taught that lesson (say 4 or 5 a class), with instruction on proper completion of the sign, demo-ing the sign with a trained dog, then group practice of that sign for 5 minutes or so, then on to the next sign for the class. Plus, there was a lesson plan book you got at the end of lesson 1, that covered all the lessons (8 weeks, now its compressed into 7 weeks), and what was covered in each lesson, with the signs and what to do at each sign all in the back. If you took both novice and advanced rally classes, you essentially got all the rally signs, and how to do them, plus the written lesson plan book for them all.
When the class was on the floor all working on a sign, the instructor and assistants would come through and give pointers to the different teams.
Maybe take the instructor aside before next class and ask if you're supposed to know the signs already before the class?
