What is the ruling on mixed-gender education that leads to missing prayers and neglecting the pursuit of Islamic knowledge, especially with the presence of misleading subjects and immodestly dressed female teachers, and with the parents' objection to abandoning this education?

If studying in mixed-gender schools is necessary to achieve a benefit for you or for Muslims, and there are no alternative শরিয়াহ-compliant schools, then it is permissible to continue, provided you adhere to the following: maintaining prayer, lowering your gaze, being cautious of seclusion, and being mindful of incorrect ideas. However, if the knowledge is not essential, or if it can be acquired in places that adhere to the Sharia, then it is not permissible to continue. If you do continue, invest your time in learning the rulings of the religion.
