RAS Prelims vs UPSC Prelims — Syllabus, Difficulty, Overlap
Point-by-point comparison of RAS (RPSC) Prelims and UPSC (CSE) Prelims: syllabus overlap, difficulty, negative marking, and whether one prep works for both.
Aspirants routinely ask whether UPSC preparation covers RAS. The answer is nuanced: the national portion overlaps heavily, but the Rajasthan-specific portion (roughly 40% of RAS Prelims) has no UPSC equivalent.
Head-to-head
| Parameter | RAS Prelims | UPSC Prelims |
|---|---|---|
| Conducting body | RPSC | UPSC |
| Papers | 1 (GS) | 2 (GS + CSAT) |
| Questions | 150 | 100 + 80 |
| Marks | 200 | 200 + 200 |
| Duration | 3 hours | 2 + 2 hours |
| Negative marking | 1/3 | 1/3 |
| Rajasthan-specific | ~40% | 0% |
| Cut-off (est.) | 70-85 | 88-98 |
Syllabus overlap
- Indian Polity, Modern History, Economy, Environment, Science & Tech — 70-80% overlap.
- World Geography, International Relations — partial overlap.
- Rajasthan Polity, History, Art & Culture, Geography, Economy — RAS-only.
- CSAT (aptitude) — UPSC-only.
Bottom line: UPSC prep gives you a strong head start for the national portion of RAS, but you must add ~3 months of dedicated Rajasthan-specific preparation. Every Rajasthan PYQ on this portal is tagged by micro-theme to make that faster.
