I really prefer my students contacting me through my e-mail that I check daily:

(e-mail) a.petrova@nkaidh.ru

During the semester workdays, the best option is always face-to-face:

(workplace) Room 42, Automobile Department , Novosibirsk College of Automotive Service and Road Facilities, second building

For less formal conversations, feel free to access my profile at our social network:

(vkontakte.ru)

Anyway, I'm always glad to hear from you.
