Schwser Mock 1 and question 3 F

Hi

For 3F in schweser mock 1 , i am thinking why have they mentioned and used AUD 5% in calculating forward risk premium ?? I guess here we are talking about French/EUR where french is domestic currency and forward premium discount is equal to domestic Rf - Foreign Rf .why have they used AUD 5%?

Can somebody provide scheweser mock errata for all the exams ?
