B School that Allows Undergrad to take Grad Courses

[SophiaPrincess]

Note these provisions in the 2024-2025 Federal Student Aid Handbook, Volume 7 Chapter 1, Student Eligibility for Pell Grants:

For the Pell Grant program, a student is an undergraduate only if the student has not earned or completed the requirements for a bachelor’s or professional degree. […]

Occasionally a student will complete all the requirements for a bachelor’s degree but will continue taking undergraduate courses without accepting the degree. Your school must decide whether and at what point the student completed the baccalaureate course of study. If your school determines that the student did complete a bachelor’s program (regardless of whether the student accepted the degree), then the student is no longer eligible to receive a Pell Grant. […]

A student may not receive Pell Grant payments concurrently from more than one school. If a student is awarded Pell for any period of concurrent enrollment, the student has the choice of which award to receive but is limited to a single award from a single school.

If it wouldn't break any rules, I was planning to pause my bachelor's with one or two classes remaining and take graduate classes in business at another university. After completing as many graduate courses as allowed, I will return to finish my bachelor's degree. Is there a better way?
