I know that all people aren't equally gifted in all areas. I know that well and I am always friendly with students. You can ask me anything about the subject. starting from silly things to your imaginations. I will help you with all these . If you ask me something that I do not know, you can always count on me to learn it and then teach you. I speak English and Deutsch too, but I teach in English only. My Deutsch is not good enough to teach.
