What is the ruling of the Sharia on studying in co-educational schools with the presence of the hijab, knowing that abandoning studies leads to legal accountability by the Israeli police?

Mixing in educational stages is one of the reprehensible acts that came about through imitation of non-Muslims, contradicting His (Allah's) saying, "And abide in your houses and do not display yourselves as [was] the display of the former times of ignorance." Furthermore, Allah commanded lowering the gaze, "Tell the believing men to reduce [some] of their vision and guard their private parts... And tell the believing women to reduce [some] of their vision and guard their private parts." Studying in mixed environments is a great evil and is not permissible except in cases of extreme necessity with no alternative, and with reservation, seclusion, lowering the gaze, guarding one's private parts, minimizing evil as much as possible, and choosing righteous companionship.
