<p>The Williams [url=<a href=“Williams College”>Williams College]tutorial[/url</a>] system is based on 2 students and 1 professor. It is regarded as very popular and successful. The tutorial classes are optional, but all students are encouraged to try them.</p>
<p>Williams also has a joint program (programme?) with Exeter College, one of the oldest colleges of Oxford University. Some 25-30 Williams students (or about 5% of the junior class) are enrolled at Exeter every year.</p>
