Happy tutor, who can understand the difficulties as a beginner of the English language

I am holding a Cambridge Advance English certificate for none native speakers of English, having attended courses with STS and EF Language courses and I will put a lot of emphasis on preposition and acknowledge the various grammar and vocal differences between your native language and the English language, and encourage you to purchase an English-English dictonary, so your tuition and any new words and question that you might come across would be similar to a native speaker asking about a word. This was taught to me and it proved to be working very well.
