I contacted Katja because I was concerned about my basic grammatical knowledge, whose holes had been exposed as I tried to progress to more advanced German for my Pre-U. The lessons are both efficient and fun, as any weak spots in understanding are targeted and sorted out straight away. I most enjoyed being able to move from different styles of exercise throughout the sessions, meaning that I never got bored and the time passed quickly. My confidence in German has increased massively, as I feel able to construct sentences (written and verbal) without second guessing myself anymore. I would definitely recommend Katja!
