Like a pair of toy handcuffs, language unites people, and like a pair of cuffs with a missing key, the language bond can last a lifetime. Forge linguistic connections with today's Groupon: for $79, you get a 120-hour Advanced Certificate online course from TESOL Express (a $599 value).

TESOL Express equips English-speaking tongues to teach one of the world's most useful lexicons to non-English-speaking students. Advanced Certificate classes prepare learners to pass the internationally recognized Teaching Knowledge Test at their leisure with sessions available online at any time of day, which can open doors to securing English-teaching jobs around the world. Budding lexicographers pack their knowledge receptacles with lessons that break down the English language into digestible morsels, as well as with the fundamentals of lesson planning and classroom management. TESOL Express's specialist modules, which are elective courses that reveal tips for teaching young learners and managing large classes, keep soon-to-be teachers' minds as agile as a cheetah on a televised dancing competition. Additionally, a personal tutor is on hand to shepherd students through the course.

After successfully completing the course, students receive the TESOL Advanced Certificate, which they can then fold into a paper airplane and throw at a globe to divine their future teaching destination. Alternatively, a contact database allows graduates to search thousands of language schools around the world to discern their ideal location. For more details, check the FAQ page here.
