Fourth Wave (Harder Searches): Spend up to 3-5 minutes per question on more complex code lookups. Focus on easier calculations like basic conductor sizing and motor requirements.

Fifth Wave (Complex Calculations): Use remaining time for the most challenging questions, typically complex load calculations for dwelling units or commercial installations.

This method ensures you don't leave easy points on the table while managing your time effectively. Remember: don't change answers unless you're absolutely certain they're wrong.
