### Roadmap to Reach Specialist / Expert 1. **Division Focus:** Beginners should start in Div 3 and Div 4 rounds to build confidence with implementation. 2. **The 1-Problem Rule:** After every contest, 'upsolve' at least one problem that you were unable to solve during the active contest window. 3. **Practice by Topic:** Use Codeforces problem tags (math, greedy, dp, data structures) to target individual weaknesses.
Pro Tips
• Speed matters: faster correct submissions earn more points and avoid penalty time.
