I was attending NPTI but it shut down do to the virus. I had an agreement with the owner to withdraw at anytime so I withdrew. The reason I withdrew was the fact that the instructor could not teach the NASM textbook very well. I am a former full time engineering professor. I know good and bad teaching when I see it. He knew the subject matter but was clueless on how to properly disseminate it. He would become frustrated with us and tried to make you look stupid if you asked a question. His lectures on the NASM textbook were confusing and no better than just reading the book. I want to tell you that your lectures on the same subject are breathtaking in comparison. You simplify the material in an easily digestible manner. You do a terrific job in explaining what the authors are trying to convey and you do it well. It is obvious to me that you have spent a lot of time thinking about how to teach this subject and it really shows. I just want to say I am grateful and happy to spend this money. Thank You, Carlos
