About Robert1) I have a technical degree from an university in the US. I have made my living as an engineer for about 10 years. I have been the teacher and the student for much of my life. My accent is from the Midwest of the US which most credit with being the easiest to understand, i.e. normal. 2) I can assist you with anything you would like to learn. As I am an informal teacher I really suggest that my students have a good idea of what they want to achieve in their studies, in fact, this is often the first step!
