Profit Testing Questions Do in Fast Way

Hi,



How you guys deal with written answer questions asking for the profit signature for few years?



I find there are many calculations needed before you get the answers.



i.e. For each year we need: beginning reserve, premium, expense, interest, EDB, ESB, expected end reserve, profit vector, profit signature



I like drawing table and fill in value for each component that make up profit signature. But i feel it is still not fast enough.



Is there a good way to calculate it fast and accurate?



Also, do we need to show the formula on how we calculate each component?



Thanks!
