RAS Prelims Subject-Wise Weightage & PYQ Trends

TLDR

• RPSC RAS Prelims is one 150-question, 200-mark objective paper (General Knowledge & General Science) in 3 hours with negative marking — a screening test only, so its marks do not count toward final merit.
• Across our analysis of 5 RPSC RAS Prelims papers, the top three subjects are Current Affairs (~20% share), History (14.9%), and Polity (13.1%) — together nearly half the paper.
• The paper is broad and dynamic: Current Affairs has surged while static subjects like Geography swing hard year to year, so static + current revision must run in parallel.

RPSC RAS Prelims Exam Analysis at a Glance

The Rajasthan Administrative Service (RAS) Preliminary exam by RPSC is the first, screening stage of recruitment to Rajasthan's premier state administrative and allied services, conducted by the Rajasthan Public Service Commission (RPSC). This analysis is built on our study of 5 RPSC RAS Prelims papers (2016, 2018, 2021, 2023 and 2024) from our parsed PYQ corpus, so you can see exactly where the marks have actually come from rather than relying on guesswork. We break the paper down by subject share, year-on-year movement and the subtopics that recur most often, then translate that into a prep plan.

Here is the exam at a glance before we get into the numbers.

RPSC RAS Prelims Exam Pattern

RPSC RAS Prelims is a single objective paper — General Knowledge & General Science — carrying 150 questions for 200 marks in 3 hours, with negative marking (commonly 1/3 of the marks per wrong answer). Only the Prelims stage is a screening test, meaning your Prelims score qualifies you for the Mains but does not count toward the final merit list. Because each wrong answer carries a penalty, accuracy and smart guessing discipline matter as much as coverage.

Subject-Wise Weightage (Our PYQ Analysis)

The table below shows how questions have been distributed across subjects, based on our analysis of 5 RPSC RAS Prelims papers. "Avg share" is each subject's average proportion of the paper, "Total Qs" is the count across all five analysed years, "2024 count" is its appearance in the latest paper, and "Range/yr" shows how much it swings from year to year.

The top three blocks — Current Affairs (20%), History (14.9%) and Polity (13.1%) — account for roughly 48% of the paper, so they are non-negotiable. Current Affairs alone contributed 136 questions across our five papers, the single largest driver of marks. After that, Geography (10.9%) and Science (10.6%) form a strong second tier, while Quantitative Aptitude (7.7%) and Economics (6.8%) are smaller but reliably present blocks you cannot afford to leave blank.

Year-on-Year Trends

Average share hides how volatile some subjects are. The table below tracks the raw question count per subject across the five analysed years so you can see the direction of travel.

The clearest riser is Current Affairs, climbing from 14 questions in 2016 to 34 in 2024 — it has more than doubled and is now the backbone of the paper. The sharpest faller is Geography, which collapsed from 18 in 2023 to just 3 in 2024 after sitting around 18–20 for years; General Knowledge is similarly erratic, swinging from 27 (2016) down to 3 (2018) and back up to 21 (2021). History and Polity have also softened in the latest paper (12 and 10 respectively in 2024). The lesson: lean into Current Affairs, but never abandon the static subjects — their low 2024 counts are exactly the kind of swing that reverses in the next cycle.

Most-Tested Subtopics

Zooming into the three biggest subjects, our PYQ analysis surfaces the subtopics that recur most often across all five papers — these are where your revision hours earn the most marks.

Difficulty: What to Expect

RPSC RAS Prelims rewards breadth over depth, and the difficulty is uneven across subjects. Current Affairs is high-volume but scoring if you have followed the news cycle closely — it is where prepared candidates pull ahead. History and Polity are largely static and predictable; with focused PYQ revision they become reliable scoring zones rather than risks. The real swing factor is the dynamic mix of Geography, Science and General Knowledge, where the count lurches year to year (Geography fell to just 3 questions in 2024) — these subjects decide your final tally because they are hardest to predict. Quantitative Aptitude and Economics are small but consistent: a handful of guaranteed marks if you do not skip them. Treat Current Affairs and History/Polity as your scoring base, and treat Geography/Science/GK as the volatile tier you cushion against by keeping coverage wide.

Expected Cut-off (Indicative)

RPSC RAS Prelims cut-offs vary widely by category and from cycle to cycle, driven by paper difficulty and the number of vacancies. As an honest indicative guide only, the General-category qualifying cut-off has historically tended to fall in a broad band of roughly 70–90 marks out of 200, with reserved categories lower — but this is illustrative, not a prediction. A tougher paper or fewer vacancies pushes the cut-off down; an easier paper pushes it up. Do not anchor your target to a single number — aim comfortably above the band so normalisation and negative marking cannot sink you.

How to Use This Analysis in Your Prep

Turn the weightage into a weekly rhythm instead of a one-time read. Anchor every week around the high-share blocks, drill the swing subjects with PYQs so volatility stops surprising you, and keep Current Affairs running continuously in the background since it is now the single largest scorer.

1. 1Spend the largest share of weekly hours on Current Affairs, History and Polity — together ~48% of the paper — and revise them on a rolling cycle so nothing goes cold.
2. 2Run daily Current Affairs (it climbed to 34 questions in 2024) alongside a static subject, never in isolation, because the paper mixes both.
3. 3Drill the swing subjects — Geography, Science and General Knowledge — exclusively through PYQs, so a sudden drop or spike in their count does not throw you.
4. 4Bank the small but stable blocks (Quantitative Aptitude, Economics) with short, frequent practice — they are easy marks you should never leave blank.
5. 5Practise full PYQ sets under timed, negative-marking conditions so your accuracy and guessing discipline are exam-ready.

How PSCPrep.ai Helps You Crack RPSC RAS Prelims

PSCPrep.ai turns this analysis into a working prep loop. Every RPSC RAS PYQ is tagged at the subtopic level, so you get topper-trusted, data-driven insights into exactly which strands repeat — not vague advice to "revise more." After each attempt you get post-attempt analytics showing your accuracy by subject and subtopic, the adaptive planner reschedules your weak areas, and spaced-repetition review keeps high-frequency facts from fading before exam day. It is the difference between reading about weightage and actually drilling against it.
