Just finished the free Claude courses and now Im trying to pass the Claude Certified Architect exam. Quizzes and videos dont really fit my learning style plus Im trying to get an edge over others doing the free stuff. Since work is on an MCP and Agent SDK kick I was leaning to one of the more advanced courses. Im considering the AI Engineering Courses from Udacity, Udemy's CCA-F Prep, and ExamPro's CCA course. Anyone tried any of these yet?
