Why do you think the 'top' maths coaching centres have a screening process? Why do you think they weed out some students?
I never actually thought about this carefully, lol.
They have a screening process to filter less advanced students or to put the student in the right class.
Reasons to weed out some students:
1. The tutoring centres don't want you to waste money if your child cannot handle their pace.
2. They do this to boost their recognition, credibility and income. With a population of let's say "above-average intelligence", these students will most likely excel in their studies from tutoring and thus giving the tutoring centre a better name, evident by what they get in the HSC. This would attract more people since they think going to this tutoring centre will yield brilliant marks. However, to prevent the influx of mathematically-inept students ruining their image through unspectacular marks, the screening process is used.
3. An exception is Ngo & Sons where they filter out unwilling students since there are so many applicants and people waiting in queue. i.e. lack of supply for excess demand.
Why doesn't the 'top' maths coaching centres accept mathematically-inept students?
I have touched a bit on this but let's suppose they let in these students. Since they are mathematically-inept, then it is likely that the teachers will find it hard to teach them even if the class is at a reasonably low pace.
Eventually, these students will leave due to poor teaching quality, thereby having a detrimental effect on the coaching centre's reputation through word of mouth, online review, etc. (i.e. revealing the true teaching quality of some employees.)
It
could be that the teachers are there for only the money and do not care much about the student's progress, so it is better to accept bright students since they are easy to teach.
I'd love to hear your opinions on this topic.
