@coder_voder: You can refer to this thread, it’s a group dedicated to INOI preparation, it contains short video tutorials, previous year problems, and their solutions.

this question might be of help. regarding topics i feel dp and graphs are most widely asked. and regarding cut-offs ; don’t think that they release any official cut-off’s for INOI.One suggestion - You should definately complete the questions on IARCS judge they are just 44 but cover most of the topics.
Best of luck for your preparations.For any querrys comment below,

  4. Doing all the past years ZCO and INOI problems.
  5. Doing more and more problems in c++.
  6. I have joined the community of IOI at

That’s it.

Can i know from which channel of YouTube you are learning C++?

I also have a doubt: Can I compile programs and run them at the INOI in the Dev-C++ environment…??

@animesh_f that is one of the best ones even I found. I also liked the hackerearth and geekforgeeks tutorial. @coder_voder I am learning c++ randomly from youtube so I can’t really say which channel.

@mathecodician you are really doing great i hope you will qualify for INOI.

@coder_voder Thanks but I don’t think there is a very good chance although I am trying my best because I don’t know graphs till now and also I am very less c++.
Best of luck to you as well.
