Proportionate Method and Interest Pooling Method

In the CFAI EOC questions, it askes several questions relating to Joint Venture and their use in Proportionate and Interest Pooling methods.

E.g reading 19, questions 10 and 19

Schweser Notes do not talk about these two methods and says that Joint Venture is required to use the Equity Method.

Can someone clarify if I should study for these two additional methods??
