Keep your working area at school neat. Koreans are very clean and neat people by nature and they will appreciate you being the same. Organized note keeping, reports, and lesson plans will go a long way in presenting yourself positively to your director. Remember also that Koreans will drop by and visit you sometimes at home, in the weekends especially so keeping your apartment neat and tidy is a big yes.

This also extends to you. By staying clean and dressing neatly you will give a great impression to visiting parents.
