Help me with NEXT YEAR course selection!

<p>Hi, I am an international student who is studying in New Jersey.
My freshman grade was pretty good. (High 3) However, my sophomore grade was horrible (High 2 - Low 3). Next year (junior year) I am approved for AP Calculus AB or BC. (This is my only honors/AP class in Junior year).</p>

<p>Will it be better if I get an A in Calculus AB or B+ in BC?
I am confused because AP calculus is going to be my ONLY AP/Honor class.</p>

<p>-Is it okay even though I only take 1 AP in junior year? Can I still go to my goal colleges? (Cornell, Emory, Carnegie Mellon, NYU, Etc.)</p>

<p>Thanks in advance!!!</p>
