Is it permissible for students to learn from a woman whose hair is uncovered in a prescribed academic subject?

It is impermissible to study under unveiled women unless there is an absolute necessity or an urgent need, due to the exposure to temptation involved. Whoever is compelled to do so must exercise caution, lower their gaze, and guard their chastity, while being careful not to be alone with the female teacher. They should also strive to minimize the evil and choose righteous companionship that helps them lower their gaze and guard their chastity.
