How many C's are acceptable?

<p>Hello, I have significantly affected by this thing called senioritis; my grades have gone down significantly, and now I have two C’s unfortunately. I am taking 8 classes and getting C’s in AP Literature and AP Biology. I used to be an extremely hard-working, energetic person, but nowadays I feel always lethargic. I don’t skip classes though. I got accepted to an ivy, but I am so worried because of this. I recently went thru a lot of s<strong><em>, including rejection from a girl, frequent arguments w/ my parents, and an ankle injury, that caused me to be depressed. I think all this s</em></strong> has contributed to my slump. Now I am feeling better and more energetic because my ankle has recovered, and I am getting along w/ my parents, but I am so worried because of my two C’s. I am sure I won’t fail any class, but how many C’s are acceptable? I don’t want my admission to be rescinded. I need some sincere answers from those who really know about college admissions stuff. Thank you.</p>
