Is it obligatory for a female teacher to make examination questions easier for her students due to their low academic level, or should she adhere to her professional standards, knowing that not making them easier may lead to her students failing and those who are worse than them succeeding?

Exam questions should be balanced between difficult and easy to accurately measure students' levels. If most teachers make their questions easy, then fairness dictates that your questions should be at their level to avoid your students failing, and this does not affect the balance between students. It must be noted that working in mixed-gender schools is originally prohibited.
