Help me becoming 5 star

I want to become a 5 star coder. I am 3 star coder and gave up CP after mass cheating in summer contests. I know many concepts of tree, graph, DP, greedy, STL. I have a couple of months to dedicate at least 5 6 hours daily . I want to become 5 star, I’d really appreciate if someone guide me. I recently had huge loss in ranking when I gathered courage to try again. Please help if you can.
