If you want, next step I can:

• Turn this into a course brochure outline for your website (with sections like “What you will learn” + “Number of questions per theme”), or
• Break it into a test‑plan micro‑syllabus exactly like your 30‑test GS schedule (e.g., “Prelims Geography Test 1: Earth & Geomorphology”, with 3–4 bullet micro‑topics under each).
