HapKiDo = TaeKwanDo plus extra stuff similar to judo, jujitsu and akido minus poomsae or kata or dance routine

Because TaeKwanDo has a small number of throws

Some TaeKwanDo instructors who never took HapKiDo lie and tell students they are teaching them both HapKiDo & TaeKwanDo but just teach them throws from TaeKwanDo & call them HapKiDo throws without teaching them throws unique to HapKiDo that are not in TaeKwanDo

How would a new student who never took HapKiDo know if they are being scammed
