I know everyone will hate me for saying this but the night b4 the exam i had the option to either study the ratios OR read the finance sections of the coca cola and qanta case studies. So i was like screw the ratios, and read the finance case studies. This was only a snap decision based on my prediction that global and finance were definitely going to be in the ext response section.
So when I realise that the ratio wasnt in the short answers, it was a HUGE relief but at the same time i checked twice to make sure that i didnt miss seeing it.
