<p>181818: In my case, my school was an IB school. However, IB classes were ranked the same as non-IB classes. So a 4.0 student was rank 1/400 or so regardless of one’s class distributions. We had 19 valedictorian 4.0 students in my year, and so such a figure devalues its inherent worth since admissions officers don’t really know where you stand among those 19. I had the hardest courseload and highest grades out of my peers, so I had my GC mention that despite the way our school ranked, I technically was the highest-performing student of the class (with an average of 97% or so in all my classes). I figured it helped a lot in admissions, because being at the upper end of that 19/400 says a lot more than being at the lower end (I had really good test scores so I figure they could have made a reasonable guess anyway, but I wanted to ensure admissions officers had the clearest picture of my application possible in terms of where I stood).</p>
