I am a 30-something Filipino ex-pre nursing student who'll be starting a Georgia nursing program in the fall. With only 7 years of US residency, I never had American instructors back in the Philippines, but nevertheless have recognized only competent instructors, regardless of their nationalities. My first med micro prof was a brilliant American researcher, who read pages and pages of slides, who's class I just had to drop along with 75% of the class. But a Korean prof held a full house with raving reviews. This said, regard all instructors as the professionals which they are: Some suck at teaching, while some inspire. "Instructor review" websites have become an invaluable tool for me in picking the best instructor in my school.
