CELE Geotechnical EngineeringSoil Properties and Phase RelationshipsSlides

If you commute to a CELE review centre (or watch Super Tutor on the jeepney), these Soil Properties and Phase Relationships slides are designed for exactly that. Each slide holds one idea, one visual cue, and one PRC-style question pattern — ready for quick bursts of review between stops.

Exam context

For the Civil Engineer Licensure Examination, Professional Regulation Commission (PRC) — Board of Civil Engineering tests Geotechnical Engineering under a "Core" label, with Soil Properties and Phase Relationships in the 1st slot across 11 chapters. CELE candidates must clear the 70% weighted average, no sub-test below 50% cut on the 2026 paper, which draws about a meaningful share of Geotechnical Engineering questions. Date to watch: May and November 2026.
