All entrants swore the same oath regardless of category, and some Fellows were permitted to dine in Clerks' Commons as it cost less, making it difficult for academics to sometimes distinguish between the two – Walker, the editor of the Black Books, maintains that the two categories were one and the same.
Alle anmeldte måtte sværge den samme ed uanset kategori, og en del fik tilladelse til at spise i Clerks' Commons da det kostede mindre, noget som gjorde det vanskelligt for akademikere at skelne mellem de to — faktisk har Walker, redaktør af de sorte bøger, opretholdt at de to kategorier var et og det samme.
