What do toppers' say about ClearIAS?

Meera K IAS

"The ClearIAS platform is highly user-friendly. It is quite easy to revise mock exams on the ClearIAS mobile app. The explanations are short, crisp and clear.

I practised and revised ClearIAS online mock exams from my mobile whenever I got time. It really helped me in my prelims preparation. The all-India ranking helped me to analyse my performance at a pan-India level even before the actual UPSC exam. Thank you ClearIAS”
