Actually, it's enough to be at approximately same level as your peers. Varying interests will balance things out. You might feel that some of your peers are stronger in math, but that biology is your thing and so on. Skill-based splitting is also a good thing for at least one subject: foreign languages. Practicing with peers on a very different level will not work out at all. And by the way, if your kid ends up being the best in the class for virtually everything, you need to move him somewhere where they will challenge him more. If you don't, then good luck later on.
