<p>Also, especially with Chinese and Spanish, a lot of native speakers take the tests. There’s very little curve because native speakers are good, so non native speakers are sometimes encouraged not to take the tests, pushing up the passage rate. One of my friends who spoke 100% Chinese at home was actually afraid to try the AP Chinese exam and the Chinese SAT II because she didn’t think she’d do well. She left China when she was really little, so maybe not.</p>
