If your dc are doing well academically, great.
You can now focus on the other things that will make them popular, confident, well rounded individuals such as sports, music and arts and crafts, learning different languages and writing systems, cooking, looking after pets, helping in home and garden etc.
Trips to museums, historical sites, projects they can do themselves about the incredibly interesting place they live in so will be a record all their lives: the lists are endless.
How fortunate you are to live in such a place, full of rich and interesting relics, places, and people.
Focus on giving your dc opportunities to make friends and 'up' their confidence and social skills.
Focusing dc to be polite, helpful and well mannered is sometimes harder than focusing on the academic side but please give it a go otherwise you'll be in the sad position of thinking your dc are special but everyone will think of them as a pain.
V.bright dc can be fast tracked eg going to university early but it isn't good for them as academically they may be superb but often their emotional/social skills are underdeveloped (backward even) oh dear, you wouldn't want that.
