<p>Many high schools only offer a few languages–German, Spanish, French, for example. He will probably have many classmates without any prior language although the ones who have four years of high school language and start in the first level for an easy grade are really annoying. He should go for a language he has some interest in. Foreign language study at the high school level depends so much on how good the teacher was. There is such a variety of abilities. Good luck.</p>
