Multiple cell/2-column formula problem

I am stuck finding a formula to do the following:

Column A labelled Status contains either R or A
Column B labelled Result contains either F or P

I need Column C to return the following on each row:

If Status cell = R and Result cell = F then give me “Fail2” or If Status cell = R and Result cell = P then give me “Pass2” or If Status cell = A and Result cell = F then give me “Fail1” or If Status cell = A and Result cell = P then give me “Pass1”

I have tried for hours and would be so grateful for help
Many thanks
