2 months ago, I posted a blog hoping to find OI groups on CF since most sites are blocked in my country. Unfortunately, I couldn't find.
In CF blogs, for practicing to OIs, suggested is solving easier OIs. But I have only CF with 2017-2023 IZHO, 2002-2023 IOI, and some from gym. I can get some points on IZHO, but I can't solve full and IOI is hard for me.
It'd be good if you answer those questions
you can solve some OJ , ATCODER , USACO too
they can helpp u
But atcoder is blocked here. :(
oh right , sry
but usaco i think is ok
Is Vjudge available? You can solve problems there I think.
No, it's not avaiable.
I asked someone from my country who got bronze in IOI, and they said they solved a bunch of IOI past problems, but also solved many CSES problems (~230 of them). I would try some of the CSES ones until the IOI ones are more do-able.
Best of luck for IOI!
Have you read the first linked blog????????????????
Oh, sorry, I didn't. But what's stopping the use of a VPN?

look, try to use proton VPN to get access to blocked sites. I'm not sure about rates you need to reach to get medals and other stuff, but most of the blocked sites can help you very much, cses.fi helped me a lot.
Proton VPN didn't work for me. :(
did you try older versions? it may work
try freebrowser
I don't have smartphone and freebrowser doesn't support pc.
1.when you are a master (maybe)
2.gold needs High rating in IGM
3.I Guess CF is not enough,because Codeforces's problem is hard on one point,if you solve that point out,than you know how to solve the all problem,but when you are in really competive,there is maybe more than one points is important in the problem.

Btw why are many things banned in Turkmenistan
I also want to know.
people before VPN exsisted:
Some countries not only ban websites, but also ban VPNs.
Just like mine.
I believe that CodeForces is enough for training targeting IOI Gold Medal. If you include tasks from CodeForces.gym, that's far beyond enough.
Thanks for your comment. Could you answer other questions too?
Is there anything in competitive programming that codeforces is not enough for?

What I dont like about atcoder compared to codeforces is that
1) contests are too quick 2) Difficulty isn't as balanced as cf and doesn't fit to me, I mean first 4 looks easier side and next 4 looks nearly impossible and it looks complete waste of time to me to even particiapate 3) Even a bit of math heavy compared to codeforces 4) Atcoder isn't as friendly as codeforces for practice of questions. UI isn't friendly for those who want to practice 5) Last but not least it doesn't have blog or comment section to get exposed to nice ideas of other solution
Who asked? Your comment has nothing in common with this blog.
What I like in atcoder is
1) The statements are short and get straight to point without any misleading stoires One doesnt need to formalize the statement, its already formalized
Most disliked feature IMO is UI is not friendly for practice
