In an intercultural classroom some (Western) cultures are used to be very bold and blunt in their feedback. This, however, doesn’t mean that they are critical to you personally. They are only talking strongly about the ideas you presented. In our school, lecturers often organize peer feedback sessions. Make sure you participate actively and don’t be afraid to give and receive critical feedback. Just know that you learn most from mistakes. Nevertheless, compliments for good work are also very common!
