Nikhil is by far the most committed teacher I have ever met. I recently took the TELC B1. I got best score in Sprechen (73/75) , Schriftlichen Ausdruck(45/45), Sprachbaustein (24/30), Hörenverstehen. Overall result Gut for me and Sehr Gut for my wife. Wouldn't be possible without effort by Nikhil. Certificate could be photoshopped so I haven't uploaded here , but feel free to contact me if you need honest opinion . You will enjoy learning German with Nikhil. My best wishes with Nikhil.
