I dropped/enrolled the course, but there is no course reserve
Answer
First check with the Registrar to make sure everything is up to date with your courses. It can sometimes take a few days if you did any course add/drop because they must do it manually. Additionally, if you are on the wait-list for a course, the textbooks won't show for you.
If everything is okay but the course reserve still doesn't appear, please ask librarians to check it in the system at library@nu.edu.kz.
