If you have taken many acoustics classes in the past it will be somewhat of a repeat. But, the instructors are top notch and just being able to pick their brains and pick up a few pertinent tidbits made it worthwhile for me. I plan on taking the level II class later this year. My business partner took it and didn't have much acoustics knowledge before hand and he felt overwhelmed with information and had some things I had to go over with him after the class. YMMV.
