What is the ruling on women studying at university where there is mixing, especially if she adheres to the Islamic dress code?

A woman must learn the obligatory matters of her religion that are personally incumbent upon her, such as correct creed, prayer, and fasting. She should also learn what benefits her in her religious and worldly life. Every country must train a group of women in medicine to treat and deliver women, so as to dispense with men. A capable woman should undertake the education of women. If such a woman is not available, then a man, veiled, whose interaction with them is limited to what is necessary, may do so. As for mixed-gender education between men and women, it is impermissible due to the corruption that results from it.
