Need Help With My Class

<p>A few of my classmates are taking both AP Bio and AP Euro this year. However, I choose only AP Euro because I thought no one would take two AP classes. Will this hurt my rank in the class a lot? I am thinking about adding AP chemistry to my schedule since I took AP bio last year. I am a sophomore who wants to get into a top private university, not necessarily an Ivy League. I just want to know if AP chemistry is a hard class so I can make the right choice. Please help me to make this decision. Thanks.</p>
