I think you don't have to learn anything new...Just start practicing B level questions. In Contests A and B generally comprise of Brute Force, Implementation, Greedy. So for now just focus on these topics.

For B & C you don't need any algorithm. But Binary search is a common topic without this not much

See, I will tell you what I did, C doesn't(generally) use some complex data structures or some hard DP concept, what I observed at that time(when I was struggling with C) was that C generally uses some good Greedy approach or sometimes C consists of Constructive and sometimes simple Data Structure(like Set, Map, Queue, Stack etc..) and sometimes C was a Graph Problem(DFS, BFS, Connected Components, etc...). So I just started solving A2OJ C ladder which also boosted my confidence a lot. I hope this would be helpful.
