Berkeley is more expensive than Duke if you’re OOS. Yield is also an operation of scholarship grants and / or cost. Duke provides scholarship grants to OOS. Berkeley does not. And I don’t think Berkeley lost those qualified eng’g students to Duke. Those qualified students have most likely gone to MIT or Stanford or Harvard or Princeton instead. If cost would be the same for both Berkeley eng’g and Duke eng’g, it’s hard to justify on going to Duke eng’g instead. Duke eng’g is far less prestigious than Berkeley’s, and the highly qualified eng’g wannabes are fully aware of that.</p>
