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.
Black Belt training can be obtained from a variety of sources but is typically between 140 and 160 hours in duration and includes instruction in the use of statistical data analysis, designed experiments, team leadership, and project management.
