<p>No, it’s fine.</p>
<p>My brother goes to UCLA (Sophomore next year) and he got a C- in a spanish class because the teacher wanted him to graduate and know he just slacked.</p>
<p>They’ll know you just got senioritis or something and they won’t really care; especially if you’ve done well throughout your high school career leading up to this point.</p>
<p>My brother even called the admission committee and they said it’s fine, If you get one D or so it’s completely fine.</p>
<p>You should call and report it though.</p>
