In my experience, any class or assembly restricted to girls was going to be in some way degrading, like the one where we'd been convened to receive the information that from now on our bodies would be producing poisons that would need to be discharged on a monthly basis, through an unspecified orifice. The restriction of the typing requirement to girls suggested some sort of connection between our festering genitals and the need to serve in a clerical-type occupation, perhaps as a punishment.
