About TopKaro
Good exam practice should be free for every student in Rajasthan
TopKaro is owned and run by HyperBillion Private Limited, Jaipur: a team of subject experts, question writers and engineers. We build free mock tests in Hindi and English for Rajasthan government exams, following the RPSC exam pattern, so every student can practise properly wherever they live.
Why TopKaro is free
Every test, explanation and current-affairs page is free, and there is no paid plan. We don't lock your own results or explanations, and we don't run countdown offers.
How every test is made
- Built from the official syllabusEach test follows the RPSC syllabus and the subject split of recent papers, so practice feels like the exam.
- Written in Hindi and EnglishEvery question, option and explanation is in both languages. You can switch during the test.
- Checked by a second reviewerEvery answer is checked again against official notifications (such as RPSC) and reliable published sources, including PIB and other government news. Questions with doubtful facts are replaced.
- No repeatsNew questions are compared with our whole question bank, so the same fact is not tested twice.
- Corrected when you spot a mistakeAny student can report a question. We review every report and fix the question for everyone.
