This course surpassed my expectations which were quite high based on my having attended a two-hour seminar Cal gave at an NGH convention several years ago. The presentation of the material is first rate. The instructor is easily able to impart his knowledge in a manner that holds everyone’s attention. He answered all questions completely. Cal obtained participation and involvement from all the students that added to the success of the course. Demonstrations & videos are excellent and help the students to grasp the essence of the theory. Student practice sessions are daily, well planned & well monitored. Corrections are made on the spot so the students can make progress quickly. Overall, a great course!
