# What are the hardest problems that have been featured on brilliant.org?

Is there an archive somewhere? If not, can you guys post which ones you remember that were the hardest? I want some practice.

I remember one from maybe 4 months ago where it had some stuff about a polynomial and it asked to find the sum of $$f(10)$$ over all such polynomials and the answer was $$360$$ or something. I remember seeing only like 25 ppl solved it so I was like woww lol · 2 years, 9 months ago
