Even in my normal school, better students will be housed in the same class. This is to make the class easier to teach and learn. Imagine there is no unwanted attention from students, teachers will be able to "teach". Where else in a not so good class, there will be endless distractions. Alot of time will be wasted teaching these students. Consequence will be less teachings and poor results.
Can't blame Hwa Chong or Raffles for having low cut off points.
