Mr. Theo Young is the greatest API 570 instructor I have ever had. The way he takes time to help everyone understand with visuals throughout his unique power points helps everyone truly understand what is being given in the code. The extra quizzes, homework, and tests help you be confident in passing the exam. Mr. Young always went out of his way to show up early and stay late, leaving the doors open for questions at any time. I just hope he starts 510 soon.
