sorry if this question don't make any sense for most people ( downvote and continue your day :), but if this question make sense to anyone please tell me, in my country most college training includes 2 levels of cp but in my college their only one level avaiabe for losers like me and the topics are someway very easy like loops and conditions maybe some basic algorithms like binary search and some stls the question is what is in level 2, i don't ask what can i learn next but i ask if there is a list or maybe public group for level 2 so i can train in a systematic way.
