I remember helping out other kids in my class. I never felt like I was more than them or had any other negative feelings. What I do remember is being really happy that I didn't have to just sit being bored waiting for other to do their thing. I loved it as a way to kill time. There was no such thing as reading books when you were done. In fact being caught while reading book in class, even when you had everything finished resulted in a major disciplinary actions! So anything that would let me not be bored always waiting for something was HUGE for me. I also still remember how frustrated I was when they'd not let me get ahead in the book / work sheets. Oh, all these memories that are coming back to me seeing my kids turning out to be just like their mommy, or even "worse", they are taking it all one step ! lol
DS4.5 is only in pre-K but his teacher did mention that he helps a lot too.
