AP and College Admissions

Do colleges see AP test score grades? Do they care if I send them? I was going to register for a few but I couldn’t because I had passed the deadline (so I have to take them next year). But, by that time, I will be a senior and will be accepted to a college already so it won’t matter really (until in college). Did I make a blunder by not taking those exams earlier (colleges will see less of my proficiency in a particular area)?

You should aways take the AP exam if you have taken an AP course in your school because it will seem fishy if you do not. Colleges will see your AP scores if they send them, but it is not the largest factor in admissions.
