FAQs
UPSC Prelims Test Series 2027: Frequently Asked Questions
What is in the UPSC Prelims Test Series 2027?
The series has 67 tests for UPSC CSE Prelims 2027. There are 15 GS sectional tests, one for each area of the General Studies syllabus, 17 current affairs tests, 20 full-length GS Paper I mock tests and 15 CSAT tests for Paper II. Each GS test has 100 questions and each CSAT test has 80, so the series holds 6,400 questions, all in English and Hindi.
Which tests are available now, and when will the others be released?
GS Sectional Tests 1–14, the Current Affairs Tests for January–September 2026 and all 15 CSAT tests are available now.
The October 2026 Current Affairs Test will be released in the first week of November 2026. Each subsequent monthly test, covering November 2026 to April 2027, will be released in the first week of the following month. This brings the total to 16 monthly current affairs tests, followed by a consolidated revision test in the first week of May 2027, covering the entire period from January 2026 to April 2027.
GS Sectional Test 15, covering the Union Budget and Economic Survey, will be released after the Union Budget in February 2027. The 20 full-length UPSC Prelims GS Paper I tests will begin releasing in February 2027, with one new test every five days.
Purchase now to access every test already released immediately, with upcoming tests delivered automatically as they become available.
How do I receive the tests after payment?
Every test comes in two PDF booklets:
- Questions Booklet: Contains all questions for the test.
- Answers and Explanations Booklet: Contains the correct answers and detailed explanations for every question.
After successful payment, both booklets are personalised with your name and order number, printed on every page. Download links are emailed to you within minutes of purchase. You can also access the same files anytime through the Downloads section of your account.
As new tests included in your purchased package or combo are released, they are automatically added to your account. You will also receive an email notification when each new test becomes available.
Are these UPSC mock tests available in Hindi?
Yes. Every question and every explanation is in both English and Hindi, as in the UPSC paper, so one purchase serves either medium.
Is there negative marking in UPSC Prelims, and do these tests follow it?
Yes. In both GS Paper I and CSAT, a wrong answer costs one-third of the marks for that question, and a question left blank costs nothing. The tests follow the same rule, so you can score yourself exactly as UPSC would.
What does the UPSC CSAT Test Series cover?
CSAT is General Studies Paper II of the UPSC Civil Services Preliminary Examination. It is a 200-mark qualifying paper with a two-hour duration. Each test in this series contains 80 questions, modelled on recent UPSC CSAT papers.
The 15-test UPSC CSAT Test Series covers the following syllabus areas:
- Reading comprehension.
- Interpersonal skills, including communication skills.
- Logical reasoning and analytical ability.
- General mental ability.
- Basic numeracy.
- Data interpretation and data sufficiency.
CSAT is qualifying in nature, and candidates must secure at least 33% (66 out of 200 marks) to qualify. Its marks are not added to the General Studies Paper I score for Prelims merit calculation. However, failing to meet the qualifying standard in Paper II means disqualification, irrespective of how well you perform in Paper I.
What is the difference between a package and a combo?
A package gives you access to every test in a particular series. For example, the UPSC CSAT package includes all 15 CSAT tests. The package costs the same as the combined price of purchasing all its tests individually.
A combo combines multiple packages at a discounted price, making it more economical to purchase multiple test series together:
- Two packages: Save 10% on their combined individual prices.
- Three or four packages: Save 20% on their combined individual prices.
Where should I start if I am unsure?
Start with the free Starter Pack. It gives you three complete tests, a GS Paper I test, CSAT Test 1 and the January 2026 current affairs test, with the full explanations, so you can judge the series before you buy. Enter your email, confirm it, and the tests open for download.
Can I purchase individual tests and upgrade later?
Individual tests can be purchased separately. However, their purchase price cannot be adjusted or credited towards a package or combo purchased later.
To benefit from the package or combo pricing and applicable discounts, you should purchase the relevant package or combo directly.
Is there an online test or an all-India rank?
The paid tests are PDF booklets that you attempt on paper or on screen and score with the answer key. The three free Starter Pack tests can also be taken online, with a timer and an instant score. There is no all-India ranking.
Can I buy a single test instead of a package?
Yes. A GS sectional test costs ₹359, a current affairs test ₹279 and a CSAT test ₹239. Full-length tests can be bought one at a time from their release in February 2027. If you need three or more tests from one series, compare the package price first.
Can I get a refund?
Yes. A full refund is available if you request it within 7 days of payment and no file of the order has been downloaded. Open My Account, then Orders, and select Request a refund on the order. A package or combo is refunded only as a whole. The full terms are in our refund policy.
