Hello Codeforces community!
I recently reached the Expert tier, but I've noticed my rating has been hovering around the 1600s for a while now. I'm struggling to make the jump to Candidate Master and would love some advice from those who have successfully crossed this bridge.
Currently, I usually solve A, B, and C in Div. 2 rounds, but I almost always get stuck on D.
A few specific questions I have:
Practice Strategy: Should I focus mostly on solving problems rated 1700-1900, or should I be learning new, advanced algorithms?
Math vs. Implementation: I sometimes struggle with constructive algorithms and heavy math. Are there any specific resources you recommend for these?
Upsolving: How much time do you usually spend upsolving a problem before looking at the editorial?
Any advice, practice group invitations, or resource links would be highly appreciated. Thanks in advance!








Maturity is when you realize that advice doesn't work.
Clearly you haven't even tried because no sane person would ever tell you to do this
If advice doesn't work, then why are you giving him advice? Do you mean your advice doesn't work?
Crap didn't realize OP was a clanker kisser the other comments didn't load for me

Mike, please ban this cheater.
Oh, you want some advice? I suggest you don’t mistake the AI’s capabilities for your own.

I had originally written a long response, but then I realized you were just asking a trash question and wasting other people’s time.
I also stayed stuck at Expert for a long time. After a really tough journey, I finally reached Candidate Master. Although I have barely participated in Codeforces contests for nearly a year, I believe my experience is somewhat valuable for reference.
I took part in every Codeforces contest. I read the editorial right away for problems I failed during the contest. Meanwhile, I practiced plenty of problems rated 1900 to 2200 and forced myself to solve them independently.
Besides, don't get discouraged by repeated rating drops. It means you need more practice on such types of problems.
I don't do targeted practice on constructive problems.
lol
I can only say you’re not stuck at Expert, judging by how stuck I am
Surely you would have been CM by now if it was not AI cheating era
Is this a joke guys?!
You are not even newbie
