Is it permissible to review compiled exam questions after comprehensively studying the curriculum, despite administrative prohibition, due to test questions falling outside the curriculum and prescribed material?

It is permissible to review compiled questions from previous exams or similar materials prepared by teachers, and there is no reason to forbid this. However, if the questions are for upcoming exams or are similar to them, and some officials publish them without the administration's permission, then the administration has the right to prohibit this, and it is not permissible to review them.
