Sometimes, I find it really hard to understand problems on Codeforces. Even when I finally do, I often end up making small mistakes — a wrong condition, a missed edge case, or just a silly logical error. And then, when I check others’ solutions at the end, I feel regret — realizing that the problem was actually easy. It hurts to know that it wasn’t my logic, but my misunderstanding that cost me the solve. Even now, I still struggle to solve both Div.2 A and B problems within contest time, while I can easily solve 1000–1100 rated problems when practicing calmly afterward.

How can I overcome this problem? If anyone knows any effective way, please share it — I’d really appreciate your help. Finding a way to overcome this problem would be a huge help for beginners like me.

And my target is to become an Expert and Specialist before February 2026. If you could also tell me what I need to do to achieve this target, it would be very helpful.
