swim lane diagrams, regression analysis, value chain

this is it sir, i dont like swim lane diagrams, regression analysis and dont fancy value chain neither. though i have studied them verywell, i just dont like them to appear in my exam. thankfully all three of these have appeared in the last P3 exam december 2014. Im with the hope that sice they appearded the last time it wont reappear this time around for june 2015. What do you think sir?
