There's not what's happening. What's happening is (made up numbers, relative proportion a true) 1000 ALDC students qualify. 200 admit. 1000 non-ALDC students qualify, with equivalent resumes. 50 admit. Thus it's easier to get in at ALDC, all else equal, and les qualified ALDC displace "overqualified" non-ALDC, or if you believe their qualifications are truly equal and those 2000 students can't be compared to each other, ALDC get loaded dice for the random selection.
