Did you mean to ask for ideas on what topics to prepare for the training sessions? You can start off by learning basic phrases and practising pronunciation (using the help of phonetics if you want). Then you can learn about tenses and when to use each tense. There's a lot to learn about grammar. You can also learn more adjectives, adverbs, and verbs to build up your vocabulary. There's also direct speech and reported speech, the correct placement of punctuations, and clauses.
