I teach German according to the GCSE and A-Level syllabus applicable, using various exercises to improve grammar and vocab. Conversation is also a big part and I aim to hold my lessons in German - I truly believe that speaking German often is the secret to doing well at it, and by doing that a lot of the more tricky stuff (the grammar!) is picked up and incorporated automatically. The workbook I base my lessons on is Essential German Grammar by Martin Durrell, Katrin Kohl, Claudia Kaiser and Gudrun Loftus, but buying this book is not essential as I use my own worksheets and PowerPoints.
