Putting AP test I did not take on application

When I was filling out my application for both CSU’s and the common application, I put that I was taking the microeconomics AP test this May. Long story short, I decided not to take it, as I have several other AP’s that I need to prepare for. Now that I am not taking it, do I have to report to the colleges I got accepted to and tell them that I am not taking it? Does it really matter enough that they will do something crazy like rescind my admission? I am just curious whether I should contact them or not, as I do not really want to bother them with a trivial question like this if it is not serious.
Thank you for the help!

They will not rescind your admission. Tell them if you want, but it’s not a big deal.

Ok thank you for the response.
