<p>You may want to find other students who are willing to take the AMC10/12, because I think the school has to pay like $25 for ten or so tests (paying $25 for one test is quite expensive…). Or, you can take the AMC at a different school.</p>
<p>I don’t think they charge for AIME or USAMO, but they do charge if you take the alternate AIME.</p>
