Hello Codeforces community
I have good math contest background (I can solve IMO Shortlist C5-C7 with 60% success rate, went to national Math Olympiad Selection Camp in 2018 summer). However I don't have much CP experience.
What should I do to reach Codeforces Orange and USACO Platinum within christmas ?
Currently I can solve ~1.5 problems (out of 3 problems) in USACO (new) gold within around 1.5 hours and looking at past Codeforces Contests I can solve DIV 2 4-5 problems/ DIV 1 A-B very easily (within 40 minutes) (but I have difficulty implementing them: https://codeforces.com/blog/entry/61899)
I don't have much time to put on informatics since I have Math Olympiad TST's coming up soon.
