This supplement will only help you, not hurt you. It's another chance for you to plead your case and convince them you are worthy of a UC Berkeley education. So check your UC Berkeley My Application portal and check to see if you were sent a supplement. Again, this means you are borderline, and most likely a good chance of admission. [Apparently UCLA and UCSD send supplements too.] Don't panic if you did not get one. March isn't here yet. But if you did, I urge you to submit your answers.
