<p>Here is something to think about: why do you take AP classes? Do you take them to look good on an application or do you take them to get some credit once you start college? If you are taking them to look good, then by all means, take all the science APs. However, if you want a little credit, many students, especially those who are going to major in the sciences, do not use their science AP credits. Taking a bit of a variety will probably give you more credit. FWIW</p>
