AP Scores and College Admissions

<p>How much do AP scores actually factor into college admissions? Say a student has stellar grades, SAT scores, extracurriculars, all that, but scores in the 3 range on their APs.
Assuming they send those scores to colleges, how much would it impact the college's decision to admit/reject that student? What if the student chose not to send the scores? </p>

<p>Thank you for all your help. :)</p>
