# Advanced Ratings: Using Formulae

If you wish to make your ratings more dynamic then it's OK to use formulae in your rating files.

*We've provided a couple of example formulae here:*

Answer:Q3, Formula:[Q1_Cover]+[Q2_Cover], SetCover:Q4
Yes, 1000-999999, [Q4_Cover]*0.2

This formula changes the rating for Q4_Cover based on a positive answer to Q3 and the results of the Formula

SetCover:Days ([DateEnd_DateValue]-[DateStart_DateValue]).Days

This formula calculates the number of days between any two given dates.

You can use any of the conditional statements and functions in a formula and it's important to pay attention to rounding values too.
