Assalamu alaikum, As we are getting more familiar with the Arabic, here is a useful article on the Arabic root word system. InshaAllah you will find it useful. Inshaallah next class onward we'll start distributing a page a class on the common words in the Quran booklet.
According to a longitudinal study (conducted from 1998 to 2014), the average time taken to get a first-degree black belt is ten years. Of course, this duration differs among martial arts. The shortest recorded training time is four years, while the longest to get a first-degree black belt is twenty-seven years. The study measured the time taken for these martial arts: Aikido, Iaido, Judo, Jujutsu, Karate, Kenpo, Kobudo, Taekwondo and Wing Chun.
What you are asking is long does it usually take the average person at the average dojang to achieve their first blackbelt. For adults that is usually 3 years and most schools require you to be 16 or 17. Some places it may take 5 years and some will hand them out in a year or 2.t would take approximately 3-5 years training to achieve Black belt. In TKD children are awarded what is called a poom belt,jr.black belt (black/red belt) until the age of 16yrs. old.
