How much of an affect will dropping a class with a W have while going through CSU & UCs app Process

Hi, Sorry if my title was not clear enough, but basically I wanted to know how much of an affect will dropping a class with a a W while waiting to hear back from CSUs & UCs on acceptances will affect me? This will be my first dropped class with a W if that makes a difference. To make it clearer I’m basically in the middle of waiting to hear back from colleges (CSUs and UCs). I will of course notify them if I end up dropping the class. I just wanted to know how much will it affect me?

Have anyone done this before and have any insight on this? Thank You!

also sorry if this was the wrong place to make a discussion for this. I didn’t know whether I was suppose to put it on UCs or CSUs
