<p>@roderick, I believe QB selects finalists. I think out of the finalists, the students who agreed to do the college match, their applications are forwarded to the respective colleges and probably the selection of students are done by the colleges. Once the colleges are done selecting (matching) who ever the students they want and informs qb, qb at that point match the student to the college depending on the ranking the student did initially. If for eg., Student A ranked MIT, Columbia, and Rice in this order and MIT and Columbia both selected the student, the student will be matched with MIT. But as MIT is non binding, student once informed of her/his match to MIT, do not have to withdraw any other applications and can decided on a college depending on where else he/her get selected. On the other had if student A ranked Columbia as his/her top choice and MIT and Columbia both matched the student, he/she is required to attend Columbia and withdraw any other applications sent. Students who opted to do match will be matched with only one college out of up to possible 8 colleges that student initially agreed to be matched and subsequent colleges that selected the student. QB will match the student with the students top choice out of the colleges that also selected the student.</p>
