Hello, I am a student from Turkey who wants to improve in order to compete in IOI. I have reached green after 2,5 months of learning but I have a big question on my mind. What should I priortise to reach specialist? I humbly request your advise. Good day to everyone.

I would recommend solving virtual contests. You need to solve from Div2 A to C at each contest. After the contest, you should read the editorial for the questions that you couldn't solve. You shouldn't give up on a div2 C problem without getting an accepted.

Start with stop solving useless 800 rating problems. Nobody cares about your fancy 10000 days streak.

To progress, solve problem close to the rating of the ones you are currently struggle with. Learn new algorithms (optional at this level), do virtual contest, ...

Specialist requires you to solve up to C in div 2 (solve C quickly already get you to expert), or D/E in div 3 (I'm not sure about this)

    Looking at his problem solved stats through visualizer, he solves lots of 1400s-1700s as well.

Congrats young man! I see you are an aspiring IOI contestant and willing to improve. Keep up the spirit. You can do lots of virtual contests, never skip a C without understanding, train on constructive algo question types, do lots of binary search problems especially on ans, study some advanced algos that come on latter questions in contests like Combinatorics, some advanced maths, DP(very useful on games problems), also try to grasp the problem's greedy logic, if it has a greedy approach. Best of luck ^^
