Course selection help for senior year?

<p>I'm an IB Diploma candidate.</p>

<p>IB Biology 2 HL (will take both AP/IB tests)
IB LA 12 HL (will take both AP/IB tests)
IB History of the Americas HL (IB test)
IB Biochemistry Wt. (2nd semester) HL
IB Spanish 5 SL (IB test)
IB Economics SL (just because I'm interested in the class)</p>

<p>I'm not sure whether I should add on Calc 2/3 or AP Statistics. The latter would be a lighter load, especially with so many classes. Yet at the same time, I'm wondering if colleges will prefer to see Calc 2/3. I don't want to overwhelm myself with work though since Calc 2/3 is a tough class, so I honestly don't know what I should do. Maybe I should not take Econ?</p>

<p>Any and all input appreciated.
PS: I am taking Calc BC and Chem II this year, so I'm taking all of the most challenging courses my school offers, minus Physics II.</p>

<p>Advice would be appreciated. I’m honestly not sure what to do at all and have to decide by next week!</p>
