First, review: Breakdowns of how every dorm is likely to play out in this year's lottery here, here, and here.
Today, we're looking at RAs and riders. A rule change last year meant that RAs could no longer eat up entire large suites with their friends—now, they only get to pull in one friend apiece.

Yes, you have to live with an RA, but opportune suites may be there for the taking.
