<p>I'm a sophomore this year and I just started the second semester.
In my junior&senior years, I am planning to take IB Higher level sciences (chemistry & biology)
Here are my questions:</p>
<p>1) Which overlaps more with IB Higher level sciences - AP or SATII?
2) I want to self-study either AP or SATII chemistry and AP or SATII biology. Which test, AP or SATII, will be easier for me after I finish the 'first year' of IB Higher level Bio&Chem?</p>
