Should I take ap tests for IB courses?

<p>I'm planning on going into IB taking HL Bio, Hl English, HL World, Sl Math, Sl French, and Sl Chem.
Being that all of the SL classes are also 2yrs long, should I take ap tests for all of my classes as well?(minus math)
Is it better to take it after senior year or after junior year?
Would this help me look even better to top Universities to help my lead with IB?
thanks!</p>
