Not so stellar senior year? Hoping for some opinions/ chances

<p>I'm pretty worried because I just had a horrible 1st semester senior year so I was hoping for some chances/opinions so I can figure out if I should apply to more safety schools (with late admissions cycles)</p>

<p>I go to one of the top/ most competitive high schools in the US
GPA UW applied to CAS with 3.88, now 3.80 (I got a C+ in an AP class this semester too which is my first and only C) weighted was well over 4.0, 4.3ish</p>

<p>SAT SCORE: 2380 (one sitting)
All AP/ Honors Classes</p>

<p>I'm an Intel STCS Finalist
Have various state/regional level awards in areas other than scientific research.</p>

<p>I've been told my extracurriculars are the most competitive my counselor has seen in years so i wont go into details about those; its mostly my 1st semester senior transcript, how much of an impact can that have on admissions- for a place like Cornell and other ivys? and i've heard most colleges have already gone through their first round of admissions and typically decide borderline cases at this point? /:</p>

<p>Thank you so much!</p>
