Speaking English is essential these days, both for work and when traveling. Indeed, English allows you to get by absolutely everywhere, even in non-English speaking countries. I am a student in the 2nd year of a Life Sciences License, ABT = Advanced Biology Training course. I therefore speak English fluently, and master scientific English because 3/4 of my courses are held in English. I teach from kindergarten / primary to higher education. If you need help with Science courses in English, please let me know in your course request.
