I took the course for 313D last month with Mr. John Spridzans. I just want to let you know that John did an awesome job, and I was able to pass my 313 D exam from first the time. He helped me a lot by answering all my questions. He is very organized and very expert in what he does. Previously I did my G3 and G2 licenses with him and I passed it from first time as well.
