All it does is slow down students learning and we want the smart kids to excel and the dumb kids to still have help and get attention to let them become smart. Smart can be Smart, and Dumb can become smart being in different classes. How do you feel about this?
The smart students can excel more. However, in some schools they only push the smart ones furthurer than the less advantaged children which in my past experience is wrong. The dumb children should be pushed more so that they have the right education and grades behind them to do well in their lives. How do you feel about this?
