You can easily tell by my rating that I am not a serious type of programmer like most of you are, but I want to become one of you guys too. I am a school boy of class 9. And I know/learnt these things-

1. I have finished learning C. I code in C++ but actually inside it is C.
2. Have some basic knowledge about C++ STL library like: queue,stack,map,string,set.
3. I know what is Dynamic Programming and CAN solve easy DP problems.
4. Also know a little bit of Graph Theory.
5. I am good at math and improving everyday.

I couldn't take part in many contests before because of my exams in school. But I can most of the time (like 90%) solve problem A and B in DIV-2 Codeforces Rounds.

Now I am like lost in a lot of things in this programming world, so many things, many many interesting stuff but can't understand most (it is awful). So please tell me what can be my best step from here. Should I practice at some OJ or like learn something new etc. Also I know that there are many people out there who are like me. So your answer could be some help to them as well

P.S: I know my English is not good, sorry about that.
