Is it permissible for a female student to participate in discussions and explanations in mixed-gender lectures?

It is not permissible for a woman to work or study in a mixed-gender university due to the corruption that results from it. Obedience to parents in mixed-gender study is not obligatory because there is no obedience to a creature in disobedience to the Creator. It is permissible for a woman to speak with non-mahram men out of necessity, provided that her speech is serious, without submissiveness or incitement, for her voice is not awrah, but rather we are forbidden from being submissive in speech. A woman in a mixed environment should minimize evil as much as possible, so she should not converse with men except out of extreme necessity, and she must adhere to complete modesty.
