If you are playing at an intermediate level, I’ll bet you are playing all the scales and arpeggios you need to know, but just don’t have a label for them.
If you’ve ever played a blues, you probably played a variation on the standard root-5th-7th-octave pattern. The only other thing you need to know is the 3rd, and then you “know your arpeggios.” And if someone sat down with you and showed you the third, you’d probably go “oh yeah, I know that!”
If you are playing anything other than simple roots, you are playing portions of scales. They are really only teaching pentatonic and major scales; major and minor scales are the same scale, just starting in a different note. The three modes they are teaching (ionian, dorian and mixolydian) are just the major scale starting in different notes.
And of course the scales and arpeggios overlap/use the same notes.
If nothing else, draw a few fretboard charts over the weekend and use them as cheat sheets. You’ve got a year to memorize this stuff, and I’ll bet you already know most of it.
I think the “requirements” are listed so they don’t get raw beginners, because they don’t want to get bogged down with questions about how to tune a bass, how to fret a note, etc.
