Did lessons 3 (Basic Electronic), 4 (Digital Audio), 5 (ProTools), and 6 (Connectivity). The ProTools lesson had nothing to do with live sound, but I did it anyway.
Found a confusing error on a self test quiz, but let the school know.
Lessons with Nick were about active vs passive DI's, Lo and Hi Z, 2 different gain structure methods, A/D converters.
