This program is based upon three pillars. In the past, if you didn't live where what you wanted to learn was taught, with the exception of videos you were out of luck.
Videos can be good, but often they are too advanced or too basic.
And if you had questions, you were out of luck. With the Internet, we can transcend all this. Write in and get an answer or read one of the growing number of essays on the different aspects of DBMA curriculum that are there for you to have a reference for the overall structure and concept of the system. All the technique sequences shown on the public website are archived, with a new one never shown on the public website each month. And much, much more.
