how to improve?

Revision en1, by RE_Prince, 2024-10-18 22:15:46

I have a bit of difficulty solving problems rated around 1700, but it seems like I can only get about 1500 performance in contests or even lower than that. Why is this happening? Can someone explain it to me? Thanks in advance for ur time:)
