I'm an Erasmus student and I've had pleasure to meet a really great teacher who taught me more than anyone before. I would like to show my appreciation and thank her, but I'm leaving a week bofore the end of the course - and the grades release. I want to be polite, appreciative and show my respect not to be a "teacher's pet" (I'm an Erasmus, I don't care about the grades, just the learning experience). Should I came to her after the class and simply thank or send and e-mail or I'll be just making a fool of myself?
Thank you for your answers :)
