is it ethical to sign up at AP Central as a teacher

<p>i’m already a teacher of ap chem, ap calc bc, ap ush, ap comp&us gov, ap macro & micro econ, ap physics c: mechanics +E&M, ap stat at apcentral.
I know i’m a great teacher so versatile. ;)</p>

<p>apparently i teach AP Environmental Science, AP Spanish Language, AP U.S. History, AP World History, and AP Human Geography</p>

<p>Why can’t I register for AP central at home? For some reason there’s an error when I click the “register” button. Does this happen with anyone else?</p>
