Any experinced with teens?! HELP!

[wrldtravlr2]

I usually teach university students. For the next 5 weeks my university is running an English program for students who are between 13 and 16 years old. I am totally petrified. I will be teaching the lowest level students.

Any tips from teachers who teach this age group regularly? These students are Turkish.

Thanks in advance!
