The registration system is a fully computerized system used by NBU and College of Engineering for managing students' files and records. NBU and College of Engineering share registration systems for efficiency and economic reasons. Each student has a user name and password for accessing his records through the internet. Authorities are granted to faculty members to register grades during a certain period of time by the end of each semester, and nobody has the authority to change the grades after fixing them (Unless there is a complaint from a student or an error in recording the grades and raise a complaint by the department head and then the relevant committee college and adjusted during the first month of the beginning of the study semester). The students are allowed to add, or drop any of the registered courses for a certain period of time.
