Medical student. Depressed. Anxious. Bubbly. Coping with a smile! :D I also teach English for funds!
Jokes aside, I am a certified informal educator in molecular medicine and have been a teaching associate at my med school for a couple a of years now. Fact is, I know my way around teaching. Had many lessons. Learned from the best professors. Younger colleagues either love me for all fun we had learning neurology and genetics together or... Hate me for being a teaching associate at 23 yo.
So, I know my stuff. I know how to teach.
Is my Serbian good? Is anyone? Probably not. I have a grammar school diploma in humanities and philology.
A year and you're all set. A month and you can go rafting in Foca. A week and, well, you can go to some wild parties, get drunk (and high), and forget you ever learned this language in the first place.
