Displaying selections from dropdown menus

I am using a drowdown cell to allow users to select a rating of 0 through 3 that is followed by a description of what that rating entails. I am then using nested if statements do display the score portion of the selection, but not the description. This question may be vague but is there a way to do this without having to enter the entire string of the selection into the if statement? The end user doesn't want the descriptions separated the rankings and ideally I would like to be able to copy and paste the display formula to apply to multiple dropdowns.

example of what I have now

dropdown cell A1 options:
0- less than 10% chance of success
1- between 10% and 25% chance of success
2- between 25% and 75% chance of success
3- highly likely with greater than 75% chance of success

display cell:
=IF(A1="0- less than 10% chance of success",0,IF(A1="1- between 10% and 25% chance of success",1,IF(A1="2- between 25% and 75% chance of success",2,IF(A1="3- highly likely with greater than 75% chance of success",3))))

That helped a lot. I ended up going with HLOOKUP instead, but same gist. Thanks
It seems to be picky with where the ratings are relative to the selections (requires them to be below the rows of selections vs. above using hlookup), but still gets the job done and I can continue to play around with it.

Thanks for helping a novice

This link is a great resource for alternatives to the IF function.
