English Tutor for people who want to improve their skills in English

I am a student in Germany. I study my bachelor thesis in English for 4 years now. I graduated from a foreign language school in Bulgaria with excessive learning of English, C1 level. Also, studying English literature and a little bit of the old English language. I am focusing a lot on knowing your grammar the best you can, as well as whenever I give you words to study, for you to have all the necessary meanings you need.
