What are the fields that a woman is permitted to study, and is it permissible for her to work as a lawyer and represent others?

A woman should learn the matters of her religion first, then other sciences if circumstances permit, and she may choose the profession of teaching. It is permissible for her to study medicine and nursing, especially gynecological diseases. It is also permissible for her to act as an agent in a case, but she should not pursue the legal profession in its current form, due to the mixing (of genders) involved and her attendance at court sessions, which is impermissible for her.
