You should if you really want to, but I don't think it should matter the amount of knowledge you and your friends have, because friendship is merely friendship! :) Plus, when you tell them, it may come across as bragging and they would perceive you as a show-off. Hope this helps!

Congratulations on being gifted and getting all the opportunties what your getting :)
You knows your friends better than any of us and how does you think they will react if you tell them? Thinks about if one of your friends told you and how you would feel.
Be proud and enjoy your learning and you will meet other gifted people too in your classes and ask them their experiences too of how/if they told friends.
If it was me then I probably wouldnt but thats just me personality. I wouldnt ever get in the gifted group anyway so I doesnt really have to think about this :)

Don't go out of your way to talk about it. A lot of people are off put by people who talk about their intelligence a lot. If it comes up in a conversation, you can talk about it, but you probably won't need to tell them. Usually with people who are genuinely intelligent, they don't need to talk about their intelligence, it's obvious to everyone around you, and therefore people who are not as intelligent might feel like you're rubbing it in.
