Mind and spirit before the Seoul training

Hello, friends! My name is Gerel, and I'm Mongolian. I'm planning a trip to Seoul at the end of this month and considering taking a course in aesthetics. However, I have a question — is English sufficient during medical consultations? Should I have a Mongolian interpreter with me?

I don't think my English is very good; I'm not fluent. Talking to strangers makes me anxious, especially when listening to medical information. Therefore, I want to know — are there doctors or interpreters who speak Mongolian here? Or do most clinics only handle English?

I'd like to hear from those who have taken courses here. Were you anxious about the language before your training in Seoul? How did you manage? Please share any advice you have.
