You're right
For Advanced English you need related texts for the Area of Study (Belonging) and for Module C (either conflicting perspectives or history and memory). Generally the BOS says at least TWO texts so i'd go for three just to be sure.
For Standard English you need related texts for the Area of Study (Belonging) and for Module A (Distinctly Visual - not sure about the other option) and i'm not too sure about Module C.
None of these courses require related texts for Module B which is a close study of text.
