Can I register for ECON X499.4 or SIP electives while I'm completing their respective course prerequisites?

Yes.  However, the self enrollment system does not allow students to bypass the prerequisites while concurrently enrolled. 

Students may contact PaCE Support at 805-893-4200 to enroll over the phone or in person at 2160 Kerr Hall (Office Hours: Monday - Friday, 9AM - 5PM PST).
