I am a 7th year DBA. I took the course because I liked the lecture table of contents. The lecture content is below my expectations. What I was disappointed about more than the content level was the lecture quality and sincerity. On topics that could be a little deeper, they insincerely give MSDN links and say there are more details inside. If it is a lecture, I wish I had read the terms as a standard. I read isolation as isolation, or semicolon as a comma... I doubted my eyes when I saw the chapters that were filled with text without videos. It is a miserable level that it would be much better to go to any technical blog and watch it. It seems that the lecture content management is needed even on the Infraon platform.
