how'd rock lee become a genin arent the academy students supposed to do Henge No Jutsu before they could become one? and they said he had no talent for ninjutsu or genjutsu

[PSJ]

the test to become a genin is bunshin no jutsu, no one knows how or why rock lee passed we just know he did, just leave it at that.
