and plus practise MORE

You have many sources, including USACO.org, your NOI, cp-algorithms, ...

Practice questions and learn new topics. You can solve CSES problemset, USACO Guide, CP algorithms etc

If you do usaco guide up to gold + segtrees you should have enough content for most problems. Then you just have to practice problems (cf is probably good enough, I like usaco although you will exhaust the problems you can benefit from quickly).

do not try to improve

after 50 rounds you are still newbie

I am gayy

Probably, my comment might not seem much becuz of my low rating but try solving harder problems(1200 to 1600) and not just problems at u r level.

I'm still far from being a strong competitive programmer, but one thing I've slowly realized is that progress in CP is often hard to notice while you're making it.

At first, a lot of problems feel impossible. Then one day you see a similar idea again and think, "I've seen something like this before."

I think that's how most of us improve — not by suddenly becoming much smarter, but by slowly turning unfamiliar ideas into familiar ones.

So maybe being stuck doesn't always mean you're not improving. Sometimes you're just in the part of the process where the progress isn't visible yet.

Just play some games first. Then join more contests. You can try ATCODER. Remember to try to solve (with editorial) more one problem.

You need to try to solve 4 problems in ABC.

Over 90% of the 466 problems you've solved are rated 1100 or less, try solving harder problems. I'd recommend the going through the CP-31 sheet, start at the 1200 or 1300 problems and move up from there.
