Where does your understanding come from? I'd imagine that educating less-gifted (intellectually or socioeconomically) students would be more expensive. To some extent, I can imagine there being additional costs to providing advanced education, such as if you need to higher better qualified teachers, or if somehow the textbooks are more expensive. And there might be costs in providing multiple tracks, such as having additional teachers, which could occur depending on the number of students. But I can also imagine advanced students' classes requiring fewer teaching assistants, fewer educational commodities (calculators, laptops), perhaps.
