The last day to add course(s) is one(1) week before the commencement of the semester for new students and one(1) after the commencement of the semester for continuing students.
If you drop a course latest by the 9th week of the semester, it will be officially removed from your record and will not appear in your transcript. A course withdrawal process is undertaken when you miss the drop course deadline and are unable/not ready to sit for the final exam of the course. By applying for withdrawal of course, the course will still appear in your transcript but with a "W" grade (withdrawal with permission).
Students who have been formally enrolled may apply for deferment of studies (leave of absence) for any particular semester thereafter. Students who have formally applied and obtained approval for deferment of studies will not have to re-apply for admission when they intend to continue their studies later.
