An instructor is always encouraged to bring their own style, and knowledge to the classroom. That being said, the work is copyrighted and may not be copied or reproduced in any way. It has its own ISP curriculum number, and that number is only valid if CLiC is indeed what you are teaching. If you mix two curriculums, where that you have taught part of one, and part of another, then you have in fact not taught either. We do not allow copyright infringements of any type. Not trying to be rude, just trying to answer the question.
