Can I take a seminar if I am a junior? Can I take it if I am not a declared major?

Yes, but only if space permits. Juniors, non-declared students and students taking a second seminar may take a senior seminar provided that they have completed the prerequisites and there are seats available in the seminar beginning in the second week of classes. You may attend the first meeting of a seminar that you are interested in without being registered. Contact the department early in the second week of classes to see if seats are available in the seminar that you prefer.
