<p>Depending on the subject matter, there may be a CLEP exam (or equivalent exam through another testing company) that your son could take for college credit. He could also check with the specific department at the college he ultimately attends to find out if an exemption/placement exam covering this material is available. Clearly, he’s not going to get a score for this AP exam, but he may be able to get credit or placement for the subject through other means.</p>
