Global knowledge has amazing LMS. I took Azure training and course delivery by the instructor named Shivam Sharma was very excellent. Instead of PowerPoint, he used Microsoft Whiteboard to help us understand the key topics what made things easier for people to understand. In teaching, we usually say "if we can't explain to someone, we need to understand it as well". He could literally explain things in details for the people new to the subject what made things bit slower but effective for all the people compare to only benefiting people who had some experience/knowledge in the matters.
