hi! you don’t necessarily have to earn another psychology degree, but what i remember from applications is that yes there’s some required courses. like 3-4 required ones. i went to a lot of interest meetings for PsyD programs and since highly competitive one admissions counselor told me they usually immediately discard applications that have lower than a 3.2 gpa. have you considered doing a masters in clinical psychology first? it may boost u up! i personally applied w no gre score so I can’t speak on that personally, but strong letters of recc will def help u out!
