How To Learn A Concept Visually

  1. Open a track and pick a concept section from top to bottom.
  2. Read the concept map chips under that section (core techniques + data structures).
  3. Solve easy examples first, then medium, then hard in the same concept.
  4. Use the problem page hints/pitfalls before looking at the reference solution.
