To receive special permission, please go to Swann 201 and fill out the Special Permit Request form. You will be asked to see the Japanese instructors to determine your appropriate level of Japanese. Applying for special permission does not guarantee you a spot in the class. Once you submit your request, you MUST attend the first class. Actual permission to selected students will be issued after the first class.
Some people do drop the course after the first class, so keep trying to register.
If the class is not yet closed but you cannot register for it because you have a minor time conflict, you may qualify for a time overload. Time overload is permitted only if you can attend a different section of the same class once a week or so. Contact your instructor and ask if you qualify for a time overload.
