I am really overwhelmed by all the ressources on internet and i would love some help. I am mastering all c++ basics also, I would love some help on ressources or roadmap so i can be prepared for next year's selections in our country.I know it is hard to do it in a year and i will need hardwork and real practice and i am ready to give it everything i just need help onwhat ressources to use or problems to solve because sometimes i keep solvig easy problems like 900 or 1000.I hope to see some answers i really need it this is important for me.
I would suggest doing Codeforces/Atcoder contests upsolving them and doing OI vc's , you can start from USACO Bronze which is suitable for beginners and then increase the difficulty as you improve
In my opinion, USACO Guide is a very good resource, especially for preparing for the IOI
