is pam and sheil's behavior ethical from Kantianism perspective ? discuss your answers plz

CASEANALYSIS Pam and Sheila were students at a large state university that had math and foreign language requirements. Pam was strong in languages, but lousy in math; Sheila had the opposite abilities. The two struck a deal: Pam would pose as Sheila in Sheila's Spanish class, and Sheila would pose as Pam in Pam's calculus class. For an entire semester, each attended the other's specific class, answered to the other's name, and took exams on behalf of the other. The university was so large that neither the professors nor the students in those courses knew the conspirators' true identities. The trick worked and they got A's on their permanent records for the courses. This is probably the most extreme a case of cheating that could exist. It was not a matter of copying some answers from a neighbor's test, or plagiarizing a term paper. Instead, every single requirement for both courses was fulfilled fraudulently, and neither Pam nor Sheila learned a single thing in the classes they were ducking. The risk they were taking was enormous, for, if caught, they would have been permanently expelled from their university. That, though, did not matter to either of them.
