At the moment, I'm studying Physics. Let's say that in my first year I have scored 89%. How many students on average would get that score? Does that result mean that I am on track for receiving offers of admission at MIT, Princeton...for graduate studies, given I keep getting such results in my later years? How likely is it anyway that a student keeps getting such a score in his second and third year? And would such a result, by itself, (w/o any extra-curricular activities) be sufficient to secure internships or work placements at big companies?
