RTL tests Germans’ knowledge – three-part series

In three shows (“Der große Deutsch-Test” – “The Big German Test”, “Der große IQ-Test” – “The Big IQ Test” and “Der große TV-Test” – “The Big TV Test”), viewers can put themselves to the test along with celebrities and the studio audience, who represent different groups.

Host Sonja Zietlow and co-host Wigald Boning will see who really knows their grammar, spelling and punctuation.

Kathrin Kunkel-Razum, head of the Duden editorial department, will join the show as an expert.
