The lecture content is well-organized and the problem-solving exercises were all good, but... Why did you record an example of "AWS Certified Solutions Architect - Associate" in the exam reservation video? I couldn't hear the voice properly at the beginning and just followed along to book "AWS Certified Solutions Architect - Associate", only to realize later and was shocked.. I hope this gets corrected so that others don't make the same mistake I did. Also, the lecture materials download file is named "AWS_solution_architect_associate_강의자료_v5.0".
