<p>Isn’t the answer obvious?
Unless WPI gives you a better offer, go to UCSD (lowest debt by far; good engineering.)</p>
<p>Or you could take a gap year. As you’ve now discovered, state schools usually don’t give adequate n-b aid to OOS students. If you’re waitlisted at Michigan (OOS) and UCLA, you might have had a shot at a full-need private school with good engineering such as Cornell, Johns Hopkins, or Rice. But that wouldn’t be a sure thing at all.</p>
<p>UCSD with that aid package is a good outcome.</p>
