What should I recommend for a foreign student with problems on the country language? Later this week one of my undergrad classes have their first written test and one of the students is not from my country, and he said he's been having some problems both understanding my lectures and the recommended book

And now he desperatedly sent me an email asking for advice on what to do.

The thing is: I don't know what to recommend either... I never have this case before... 
What could I indicate/advice him that would help?
He needs to improve his language skills fast...

When I studied in France (and this was engineering, which means a different vocabulary), we watched tv, worked with our French colleagues (ie other students), we helped them with English and they helped us with French... Total Immersion was what we practiced - limiting our use of our mother tongue to increase the French as fast as possible.

We also did evenings where we provided food &amp; beer / wine to increase opportunities for conversation as well as getting our work checked.

Also, watching France V England at rugby was good for a laugh... :)

Are there any courses in the institution he could enrol in? but these courses need to be accelerated...
