It has come to our attention that certain coaching centers are misusing names similar to ours, such as Vajirao or Bajirao, in an attempt to mislead and attract students/parents. Please be informed that we have no association with these fake institutes and legal proceedings have already been initiated against them before the Hon'ble Delhi High Court. We urge students and parents to stay vigilant and let us know in case they are approached by such fake institutes.

Polity and governance

Constitution, institutions, rights, public policy and governance-related current affairs.

Economy and social development

Basic concepts, Budget, Economic Survey, schemes and contemporary economic issues.

  • Identify subject-wise strengths and weak areas
  • Review explanations and update short revision notes
  • Track score and accuracy across successive tests

How to choose the best UPSC Prelims Test Series

The best test series for a particular aspirant is the one that matches the current UPSC pattern and produces useful corrective action after every attempt. Test count alone is not enough. Check whether the programme includes planned syllabus coverage, GS and CSAT simulation, detailed explanations, performance analysis and a schedule that leaves time for revision.

Practise decision-making, not only facts

UPSC Prelims requires candidates to decide which questions to attempt, manage close options and protect their score from avoidable negative marks. A timed test environment helps develop this examination temperament.

Use a test-based learning cycle

Revise the assigned subjects, attempt the paper honestly, analyse every error and revise weak areas before the next test. Repeating this cycle is more valuable than collecting mock papers without reviewing them.

Do not neglect CSAT

CSAT is qualifying, but it still requires a safe margin and dependable speed. Candidates should diagnose their weaker areas early and practise comprehension, reasoning and numeracy under time limits.
