<p>SJSU publishes data indicating that only 17.1% of frosh graduated or are still enrolled in their first declared major (which is often at application and entry, although undeclared is possible) after eight years (note: this is a moderately selective state university with some part time enrollment, and many full timers taking only 12-13 credits due to needing to work).</p>
