Reading the results claim

Selection figures are the industry’s main advertisement and they are almost always missing a denominator. "Four hundred selections" means nothing without how many enrolled. A centre that enrols twenty thousand and selects four hundred has a two per cent rate, which is a fact the poster is designed not to give you.

Ask three questions: how many students enrolled in that batch, how many appeared, and how many of the advertised achievers were enrolled for the full course rather than a short crash programme. The third one matters, because top scorers are sometimes recruited cheaply or free late in the year precisely so their names can appear on the poster.
