My teacher happened to learn all 39 hyung listed in the Soo Bahk Do Dae Gam by Hwang Kee (the hyung not taught any more where taught to him by GM Oh Sae Joon) I am a Sa (4) Dan Licenced Instructor (licenced by my teacher, with my licence registered in Krea by the Moo Duk Kwan, not the Soo Bahk Do, but the Tang Soo Do. Hwang Hyun Chul's trademarks don't effect anything in korea, so those that out-rank him still have control there.)now back to hyung:
at white belt, you learn the 3 kicho hyung
after, when you are in the intermediate levels, you begin with the first 3 pyung ahns, along with San Tjin(Sam Jin).
Then at red belt you learn the last 2 pyung ahns with the 2 Pal Che forms(Dae and So)
At Cho Dan, you learn Naihanji Cho Dan and Jun Jang
At Ee Dan, only NHJ Ee Dan(since you have to now remember everything up to date that was taught)
At Sam Dan, you learn 3 hyung, NHJ Sam Dan, Sip Sam(Seisan) and Jin De(Sip Soo)
At Sa Dan is Jindo. my teacher only told me this is how it was taught to him, in this order. to see the list of the order my teacher teaches hyung, look at the post
