This program was tough. Don't expect to get your black belt in 12 months unless you have past martial arts experience and tons of time to train to perfect techniques. The reason I say this is because you test by video submissions. This means that your videos can be slowed down, and paused, to check that your technique is perfect, or to the level of proficiency that is expected. For training, you are given an online video curriculumn through the website. You can only access videos that are for your belt level, and you move up as you pass tests. There are pre-recorded classes that you can join in on, and you can even join in on real time classes on facebook throughout the week. Don't think that you will just breeze through this because it is online. Mr. Byan makes sure of this. He will spot every little detail that is wrong in your videos and make you do it over until you perfect your technique. This kind of critique should be expected for an online program though since you don't have 1 on 1 physical contact. Another nice thing about this class is that you can contact him directly anytime and get 1 on 1 ctitique. Mr. Bryan doesn't let you take shortcuts and he will make you earn it. I already knew most of the techniques and some of the kata from past training before starting this program, and it still took me 2 years to get 1st Dan. That was training 2-5 days a week and at least an hour a day. Also, to add, he gave me the option of taking my test at his dojo in the UK, and he also holds seminars which you can attend, even if you live in another country.
If you want to make the most out of this program, find at least one other person to practice with so that you have some physical 1 on 1 training. I trained a little with my wife and my son, but mainly with one of my friends who took Tae Kwon Do. Finding an abled body will allow you to practice blocking, striking, and self defense with another person. You can train technique and conditioning by yourself but you can't really train self defense without another person. You should also at least buy a punching bag, and/or a century Bob to practice techniques by yourself. You need a target to strike.

Edit: I took this program before Covid 19 hit so Mr. Bryan may have some restrictions on testing at his dojo or joining seminars. Also, since covid 19 hit.
