<p>With the increasing popularity of CS, a CS department which cannot increase capacity (e.g. at LACs and other schools with no TAs and limited class sizes) may not be able to accommodate all students interested in taking CS courses. On the other hand, a CS department which can increase capacity easily (by adding more TAs) may end up with very large class sizes (e.g. 700+ at Harvard and Stanford, 1000+ at Berkeley) to allow all interested people to take at least the introductory CS courses.</p>
