What are the attendance rules in IIT BHU?

In IIT BHU, students are expected to attend all the classes for their respective courses. However, if for some reason students fail to attend all classes, they need to maintain a minimum of 85% attendance. The 85% attendance rule is applicable for theory classes, however, for laboratory classes students are expected to maintain 100% attendance. If any students miss lab class for some emergency they can contact the teacher concerned to make up for it. Students are allowed leave for medical emergencies provided they submit proper documentation. Many professors follow the attendance rule strictly while others may not. To be safe students should maintain a minimum of 85% attendance as the institute takes disciplinary measures for students who fail to do so.
