If you want to leave the class, you can follow these steps: First of all, you need to find your class teacher or class administrator to report your thoughts to them. If the class teacher or administrator agrees to let you leave the class, you need to fill in a leave application according to their instructions. 3. In your leave application, you need to describe in detail the reason for your departure. For example, if you need to leave the class for family reasons, you need to provide your family contact information. If your application is approved, you will need to leave the class as instructed by the class teacher or administrator. 5 If you leave the class for longer than the homeroom teacher or administrator allows, you may face some consequences. For example, you may lose the opportunity to participate in class activities or your leave may be considered truancy. In short, withdrawing from the class requires careful operation to ensure that your departure is approved by the class teacher or administrator and that your departure does not bring unnecessary trouble to the class.
