Finally hit expert, now my next target is candidate master. I'd love to hear advice from people more skilled and experienced than me. If you have CF Analytics, can you check out my profile and see what I need to start doing to solve Div 2 D consistently? I'm considering working through some key sections in CSES (Sorting and Searching to improve my binary search on answer intuition, Tree Algorithms, Graph Algorithms, DP because I suck at complex DP, and Range Queries to finally learn segment trees).

Maybe I just need to solve more problems as I've only done 230 so far.

I recently graduated from college with a degree in mathematics, but I feel like I'm not exploiting my math knowledge enough. For example, my combinatorial reasoning is good but I rarely come across problems in the Div 2 A-D range that require it. Should I start looking at later problems from competitions for those kinds of problems? I always hear that my math intuition should help me a lot in competitive programming, but so far I haven't felt that honestly.
