I guess it's not a problem to let them learn the same things despite their level. However, the teaching speed and method should adjust according to their level. But the most important point should be the real interest of those kids. We can't force them to learn something they really doesn't want.

Guess so...maybe I'll know what should I do when I see him again.:)
