Does rank 1 give a 100th percentile?

Yes, being ranked 1st in the class means you outrank everyone else, which this formula correctly returns as the 100th percentile.

Why do colleges care about percentile instead of raw rank?

A percentile normalizes rank across schools of very different sizes — being 20th out of 40 is very different from being 20th out of 800, and percentile makes that comparable.

Convert a class rank (e.g., '6th out of 51') into a percentile that shows what percentage of your class you outrank. Percentiles are often easier for colleges and scholarship committees to compare across schools of different sizes.
