Courses for Junior year?

<p>I am a rising Junior and I am having trouble deciding whether or not to take AP Statistics. I am already taking AP Economics, AP Physics B, Precalculus, Pre-AP English, and Chemistry - at my school, we have to take two years of a science before we can take them in their AP form.
However, although my Economics class will only take up one block, it is going to cover material for both the Macro and Micro exams. I have a lot of extracurricular activities, so I am worried that taking four AP's will be too much. On the other hand, in my school, we are not able to take AP classes until Junior year, so I have to cram all of the ones I want to take in the next two years.
My alternatives to AP Stats are Computer Programming (intro course), Biology, or Film and TV.
If anyone has taken these courses before, I would really appreciate if you could give me some idea on what the work-loads are like, and whether it is worth it to take 4 AP's.
Thank-you! :)</p>
