@archsadrmp: READY FOR MPLE? Part 2 🚨 Another MPLE Mistake 🎯 Keyword = Correct Reference = Correct Answer Example: The keyword is "effective decomposition." Many will answer based on the RNPCP, but this topic is actually discussed in Plumbing Design and Estimate by Max Fajardo. ✅ RNPCP: Septic tank liquid depth = 0.6 m to 1.8 m ✅ PDE: 120 cm septic tank liquid depth for effective decomposition Always identify the keyword first, then determine the correct reference. 💬 Have you ever answered a question using the wrong reference?
