Conceding lengthy math questions? test, philosophy, difficult, quantity

I’ve used this strategy before of simply not bothering on very lengthy calculations on equal weighted test before, and had good results. Should I expect to see too many portfolio standard deviation or other difficult math questions on the actual exam? I just see QBANK questions that seem unrealistic to be in mass quantity on the actual exam. Not really sure I even want to bother. Anyone else use this philosophy with success?
