Is the entire Senior class only 26 students? You say that typically 25-50% of students are admitted, however, if only 13 applied, that’s certainly not a big class, unless you’re saying of those who apply generally 25-50% get in. Illinois is trying to increase their enrollment of in state students, hence they probably accepted less from OOS. Also, if they use the track record of the students who are enrolled there, or historical information insofar as whether those students attend or not, that could be why they accepted less.
