We are happy to share that our UPSC Prelims exam 2015 answer key had accuracy of 98% when compared to official UPSC answer key. We regret that we could not get answers to 2 questions No. 54 and No. 55 (Set C) correct. For question number 11, we said it would be either D or A, and answer turns out to be D (we thought it would be A though). Next time we will try our best to increase this accuracy.
Thank you for your trust and cooperation.
