<p>I was around a B+ student my highschool life but this senior year I have around a C in AP physics and a C in AP calculus.</p>
<p>Out of the 5 schools that have sent a message back, 4 accepted. How bad do I have to be doing for them to change their decision and reject me? And how long will it be until they send me a message saying they want to reject me?</p>
<p>If you don’t have any discipline issue, your overall GPA is not significantly changed, and you did not drop out any courses without consulting the admission office first, you should be fine. For students got rescinded, it usually happens after the school receive the mid-yer or final school report.</p>
<p>You can get rescinded for:</p>
<ul>
<li>any Ds or Fs, or a calamitous drop in overall GPA</li>
<li>dropping courses</li>
<li>disciplinary/ legal problems</li>
<li>lying on the application</li>
</ul>
<p>but going from B -> C in two courses shouldn’t be the end of the world. That said, you’re getting very close to the danger zone. Stop the slide now.</p>
<p>Check the letters or the admissions portal to see if any conditions are listed. Some schools have a specific threshold (e.g. your senior year must have a certain GPA with no D or F grades), though others may have a vague “maintain your academic performance in your senior year” condition. If the latter, you may have to ask to find out what they mean.</p>
