Yep, in video game culture, ranks go like this:

F

E

D

C

B

A

S

SS

SSS

They can have numbers, in which case the higher is the lower one and vice versa. So Ginger, being an S/5 is only a single rank higher than Nicolas, who's an A/0 (A5, A4, A3, A2, A1, S5, S4, S3, S2, S1, S0 etc.), seeing as in the manga those numbers only vary from 5 to 0.
