If you are not a primary or secondary major, you will not be able to register for Spanish classes at the 200 level or above during priority registration. This paragraph under the detailed information for each course will always give you that date should you forget or need it in a subsequent semester:
"All seats restricted during the early registration period. The restriction will be lifted on May 3, 2012 by 9:00 a.m. Students must meet the prerequisite requirements for this course (found in the Catalog Entry) or will be told to drop on the first day of classes. Non-registered students are not allowed to sit in or audit."
