💡 Study Strategy for Success

Active Recall

Don't just read - try to explain algorithms out loud. Use the self-check questions to test yourself.

Practice Problems

Work through problem sets (ps1-ps8) - especially ones you struggled with. They're in Assignment_answer_sols/

Visualize

Draw out graphs, trees, and algorithm steps. Use the interactive diagrams on each topic page.

Break Time

Take 5-10 minute breaks every hour to stay sharp. Your brain needs rest to consolidate learning!
