For science subjects, I tackle all kinds of difficulties for the student by performing a series of exercises with increasing difficulty; first by explaining the course, giving out demonstrations and providing some simple examples. I refer for all this to my old courses available and those of the student, as well as my personal books of language learning. I also write writing materials that I provide to the student. I have to my credit many academic baggage and hours spent studying, including three Masters in International Business and a degree in Engineering. I invite you to ask me for a CV (completed in six languages to know more about my skills).
