Exam format

Reading about the exam format in the bpp materials it’s not clear whether a ratio question is a certainty for a long question on every paper. Can someone let me know? I’m working on the basis that consolidation p&l, sofp, single entity accounts, cash flows etc can all come up too in the long questions however it would be good to know if ratios can be expected as part of a long question in all papers so as to give it extra focus.
