Ilham got it right. A Rhodes Scholarship is one the world’s most prestigious scholastic awards. I like to use it as an example of high achievement because it requires both academic excellence as well as excellence outside of the classroom — typically in the form of interesting, exceptional accomplishment. I studied Rhodes Scholars as part of the research for my first book, so I know a little bit about them — most notably, that they tend to make use of very clever study hacks and unconventional thinking to fit in all the ambitious endeavors that brew in their minds.

From my knowledge of Rhodes Scholars, they are certain group of students every year who obtain the Rhodes scholarship from Rhodes foundation to study at Oxford University.

Now I could be wrong but this is what I have heard about Rhodes Scholars. But in this site, I believe it is taken as an expression that anyone can achieve this status, which is true because these people are like anyone else only they studied very light but got awesome grades and did some great volunteer or extracurricular work.
