National Exams, December 2019 — 18-Geol-A6, Soil Mechanics (3 hours, closed book). Six questions constitute a complete exam: Questions 1–5 are compulsory; for Question 6, candidates choose 3 of 8 optional sub-questions (5 marks each) — all 8 are solved below as a complete study resource.

Reference texts: Das, Principles of Geotechnical Engineering; Craig's Soil Mechanics (Craig & Knappett); Freeze & Cherry, Groundwater (seepage/flow-net topics).

graphically-read values (compaction curve extrapolation, oedometer Casagrande construction, flow-net equipotential positions) are flagged with individual check callouts below where the read/assumed value materially affects the answer.
