AP doesn't matter to college admission?

<p>Should I report all of my ap scores when applying for college?
I've got some 3s but I am afraid these might give a bad impression to admission officers.
Since I don't have to send out official score report till I try to get credits, I am planning on filling the scores of the subjects on which I recieved 5s and 4s in the application.</p>

<p>But can I really do that?</p>
