This is a terrible approach to teaching. I’ve been in high school classes where I played the TA role, and when I couldn’t switch to another class I started skipping. It slows down the students who learn too quickly for the class, there’s no point for smart students to drill concepts as much as the others.

As someone who was in equivalent programs in the US, I can tell you my experience was that most people in the normal classes didn’t really care, and that attitude is far more likely to discourage the 2-3 gifted students than it is for gifted students to somehow lift up all the other students.

As others have said, gifted students weren’t just smarter students, they were mostly the students who cared.
