CELE Geotechnical Engineering — Shear Strength of SoilsSlides
The slide format strips Shear Strength of Soils to the visuals that CELE reviewers remember best. Professional Regulation Commission (PRC) — Board of Civil Engineering's 2026 Geotechnical Engineering papers reward reviewers who recognise the structure of a concept before they parse the item text; these slides train that recognition.
Exam context
For the Civil Engineer Licensure Examination, Professional Regulation Commission (PRC) — Board of Civil Engineering tests Geotechnical Engineering under a "Core" label, with Shear Strength of Soils in the 7th 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.
