<p>It is only fair to allow very talented undergrads (who are ready for it) to take grad courses. At the same time, I’m also in favor of having some sort of system that stops the slightly less talented who are not mature enough (yet). It should not become a fashion. If the demand for courses taught in grad school is really high, college should offer similar classes. I realize that college does not want to include ‘professional’ courses, but it should be possible to develop “theoretical” courses that are giving the undergrads a good idea about what to expect when continuing their education in a ‘professional’ school.</p>
