If one achieves a score in the 99th percentile on an exam, is that score considered in the top 1% or 2%? How is percentile defined in statistics?
I read this somewhere: It’s top 2% - being in the x percentile doesn’t imply top (100-x) percent because the percentage getting exactly x is counted twice.
Is this correct?

If you're in the 99th percentile, 99 percent of the population is below you, so you are in the top 1 percent.
