Is Pacquiao's 'college degree' fake?

YES, it's a bogus degree, at least based on the information so far available, unless Sen. Manuel Pacquiao and the University of Makati (UMak) that issued his degree explain otherwise.

In December 2019, Pacquiao was awarded by the UMak a bachelor of science degree in political science, after a year's study (not three months) at that institution. UMak's president at the time was Abigail Binay, also Makati's mayor, after its longtime president Tomas Lopez passed away in February 2019.
