English tutor who can teach students of all age

I am Gowri Regin Shiji. I am 26 years old doing my masters in IBA in Germany. I have secured a C1 level in the IELTS test. I have been learning all my subjects in English from the age of 3 and I am confident that I can teach students English perfectly. I would like to customise the lessons according to the student‘s needs. If one wants to upskill their communication style, then the lessons will be more focused on improving pronunciation and confidence to speak the language eloquently. If one needs to focus on the writing, then the lessons will be structured in a certain way that would make children understand more about the grammatical structure and academic/professional vocabulary etc..
