UPSC Prelims 2026 Answer Key: Download GS Paper 1 and CSAT Question Paper Solutions with Cut-Off Marks
The Union Public Service Commission (UPSC) is successfully conducting the prestigious UPSC Civil Services Preliminary Examination (CSE) 2026 today, May 24, 2026, across thousands of high-security institutional centres nationwide. Over 8 lakh administrative aspirants sat for India’s toughest screening test, aiming to secure a spot in elite cadres like the Indian Administrative Service (IAS), Indian Police Service (IPS), and Indian Foreign Service (IFS). This year, the Commission has announced a total of 933 premium vacancies under the central group ‘A’ and ‘B’ structural services.
The mega offline OMR-based entrance test is organised into two mandatory evaluation blocks. The morning shift for General Studies (GS Paper 1) concluded at 11:30 AM, while the afternoon shift for the qualifying Civil Services Aptitude Test (CSAT Paper 2) runs from 02:30 PM to 04:30 PM. As candidates step out of their testing venues, the immediate priority is calculating potential score boundaries against strict negative marking criteria. In this real-time tracker, we are preparing a complete placeholder matrix for the unofficial solved answer keys for Set A, Set B, Set C, and Set D. Leading Delhi academies (like Vajiram & Ravi, Vision IAS, and Drishti IAS) are actively compiling response sheets, and the direct download links on this page will activate the moment the PDF assets go live.

How Negative Marking and Expected Cut-Off Trends
To effectively use the unofficial solutions provided below, candidates must properly factor in the marking algorithms applied by UPSC.
General Studies (Paper 1) Score Calculation
For GS Paper 1, each correct response adds exactly 2 marks to your raw total. However, a wrong answer triggers a penalty of 1/3rd of the marks, which equals a reduction of 0.66 marks. Unattempted questions carry zero penalties. Candidates generally need to balance accuracy over excessive guessing to clear the competitive threshold, which traditionally hovers around 88 to 94 marks for the unreserved category depending on paper difficulty.
CSAT (Paper 2) Qualifying Mandatory Barrier
The CSAT paper contains 80 questions worth 2.5 marks each. A wrong response deducts 0.83 marks. Unlike Paper 1, CSAT is strictly qualifying. You only need to clear a mandatory 33% barrier, which translates to a flat minimum score of 66 marks. Your GS Paper 1 score will not even be evaluated if you fail to hit this 66-mark line in CSAT.
Verifying Age Parameters for the Next Attempt
If this attempt was heavily hampered by the unexpected twist in question patterns and you want to plan your future roadmap, verifying your remaining age boundaries is essential. General candidates have a maximum cap of 32 years as of August 1, 2026. To check your exact remaining eligibility window down to the precise day, check your date profiles through rjcalculator.com.

Frequently Asked Questions (FAQs)
Q1: When will the official UPSC Prelims 2026 Answer Key be released by the Commission?
The Union Public Service Commission does not release its official, finalised institutional answer keys immediately. The official keys for the 2026 Preliminary exam will only be published on the official web portal after the entire selection process, including the Main descriptive exam and Personality Tests, is completed and the final merit ranks are declared in April 2027.
Q2: Is the CSAT marks layout counted when preparing the competitive merit list for the Main exam?
No. The Civil Services Aptitude Test (CSAT Paper 2) is strictly a qualifying paper. The marks secured in CSAT do not add to your merit rank tracking. You only need to score a flat 33% (66 marks out of 200). Your selection for the Mains exam is completely determined by your score in General Studies Paper 1, provided you have cleared the CSAT cutoff.
Q3: What is the estimated timeline for the declaration of the UPSC Prelims 2026 Result?
Following established operational trends from previous cycles, the Commission usually declares the screening results within 15 to 20 days after the exam. For the May 24 exam, candidates can realistically expect the roll-number-wise provisional selection list PDF to drop around the mid-week of June 2026.
Q4: If I am absent for GS Paper 2 (CSAT) but appeared for GS Paper 1, will my attempt be counted?
Yes, absolutely. According to official commission guidelines, if an aspirant appears in any one of the mandatory morning or afternoon shifts on the examination day, their attempt is legally recorded as consumed. If you do not want your attempt to be counted, you must remain absent from both shifts.
Q5: Can I raise an official objection against the ambiguous questions asked in today’s paper?
Yes. UPSC provides an official window called the “Question Paper Representation Portal” (QPRP). Under the modified 2026 system guidelines, candidates can log into the portal starting from the 3rd day of the examination up until 06:00 PM on the 7th day to submit their structural academic proof challenging any question.
