One payment, same for everyone, valid till the Prelims exam on 10 January 2027. GS Mock 1 and Chemistry Mock 1 are free for all. G8 Current events opens closer to the exam, so it covers the latest events; it is included when it opens. Notes, solved PYQs and the handbook are not part of a test series: they come with VKC Basic.
All 31 paid tests of both papers, Paper I General Studies and Paper II Chemistry, including tests added later, till the exam. It is a test series only: notes, solved PYQs and the handbook come with VKC Basic.
The GS pass, ₹399. Paper I General Studies is the same paper for every stream, so the GS sectionals (G1 to G8) and GS mocks are for you. GS series page.
Chemistry Mock 1 and GS Mock 1: one full-length paper for each paper of the exam, so you can judge the level, the solutions and the result page before you pay.
As soon as each one is written and checked. This page shows which tests are live. All 33 will be live before the exam on 10 January 2027.
Every test stays open till the exam. You can take each test once, at any time, and see its solutions right after you submit.
