Learning Strategy
• Attempt First: Always try solving problems without looking at solutions - even if you fail.
• Time-Box Attempts: Spend 20-30 minutes trying before checking hints or solutions.
• Understand, Don't Memorize: Focus on why the solution works, not just how it works.
• Practice Variations: Find similar problems to reinforce patterns and techniques.
• Review Regularly: Revisit solved problems after a week to test retention.
• Code Without IDE: Practice writing solutions on paper or whiteboard first.
• Explain Out Loud: Verbally explain your approach as if teaching someone else.
• Track Progress: Keep notes on which patterns you struggle with most.
