I train chito ryu yoshukai, and that doesn't sound like one of our H-Forms. H-form 3 has punching and blocking schodachi(sp?), no crosslegged stance, groin block. At yellow belt i knew Sei San, Shi Hi Sho, Ro Hi Sho, and Rho Hi Dai. I don't know if your yellow is the same kyu grade as mine. But, like I was told, "don't get in too big of a hurry, learn what you need to know at your level and learn it well".
