AP Calc AB Exam TOMORROW

<p>I don't even know why I am asking for help with this on here because without a doubt everyone will reply back saying how stupid I am and how AB Calc is soooo easy and I should have studied more diligently before today, but OH WELL.
Here's my question:
I am not prepared. What is one thing that I should know really well for the exam? I want to at least get a 2. Be as snarky as you want as long as you answer me. Please and thank you.</p>

<p>Derivitives
Limits
Integrals</p>

<p>lol</p>
