What is the difference between AP National Exam and SAT Subject Tests ?

<p>College Board administers both AP and and SAT Subject Tests. If someone receives a '5' in AP Nationals, why he or she has to take the SAT Subject Test again? I do not understand any specific reason for this except for extracting more money. It is an irony that College Board administers both the exams. They should simply have one exam for the same reason.</p>

<p>Except AP is 10X harder than the SAT</p>

<p>THey are different tests, with ap being harder</p>

<p>Colleges use them differently, so smart students take both. </p>
