No. If you are not eligible for the PSEO program (fall and spring) you cannot take courses at Normandale, even if you are willing to pay. Students may only participate in the PSEO program if they are admitted through the PSEO admissions process.
However, in the summer, you may be able to apply under a special program called SHEP (Summer High School Enrollment Program). To learn more about this exception, reach out to Admissions via phone at 952-358-8230 or via email or live chat.
