Annexure - A: Course Registration System Semester Course Load Students are normally expected to register for five courses (15 to 18 credit hours). No exception is allowed to new students. After the first semester, this limit can be changed by the Head of Department (HOD) keeping in view the students' academic situation and the list of courses offered. When a student is under warning, he/she must first register for all such courses in which he or she has failed. After that he or she should register for courses in which the points obtained are less than the minimum points required to avoid warning. Different degree programs have different minimum threshold points to avoid warning status. Registration Students admitted to International University are required to register every semester and to pay the prevalent semester fees. All students are required to register in 5 courses except those who are advised by the Faculty Adviser to do otherwise. The recommended registration procedure is as follows: 1. Appear personally to complete registration formalities. 2. For the First semester, appear for registration through Admission Office. For the rest of semesters students should register online. 3. Pay all previous fees and other dues (if any) before appearing for registration and current dues immediately after the online registration has been completed. Maximum Number of Courses Registered in a Semester 1. The undergraduate students with no academic warnings will be asked to take normal course workload, i.e., 5 courses in a regular semester. The University is not bound to offer course(s) in summer semester. However, if course(s) is/are offered, the preference would be given to final year students and then to the other batches in order of their seniority 2. Undergraduate students with academic warnings may be allowed to take 3-4 courses in a regular semester. Such students must consult their Student Advisors before registering for the courses. Correspondingly the advisor must sign the registration form/application. However, the number of courses may be allowed to increase or decrease with the written consent of the Student Advisor. For graduate students, the normal course load is three courses and the minimum is two courses. The advisor's approval is must for registration/add-drop/withdrawal purposes." Further Requirements .
