Why care to join a Test Series in the first place?

As an IAS aspirant you are not preparing for an ordinary exam. This exam requires you to be not only an individual of knowledge but also of right attitude to serve people of this country under various capacities in diverse fields and under uncertain circumstances. 

Test series, especially the one offered by InsightsIAS, prepares you for the uncertainties this exam poses you. By joining test series, you will get a plan for a year that will keep you not only busy by giving targets, but will also help you stay consistent. As you know consistency is key to success. Without a plan you will deviate soon and go off the track to spend many years of your precious life seeking success. You cannot succeed without doing adequate practicing (in a consistent manner) for the exam you are preparing. 

When you join a test series by paying certain amount of fees, you are under obligation to stay in the competition. You are under compulsion to be self-accountable. Regular tests and all India ranking will help you understand the competition and improve your skills and knowledge in a time-bound manner. There are many more benefits. As an aspirant you must seize the chance by joining early these tests and squeeze (revise multiple times) them to improve your chances of clearing this exam.

“I started with mock test papers of InsightsIAS test series and complement it with Current Affairs material of Insightsonindia. “Intelligent guessing“ article of Insights really helped me. Do go through it.

Insights online mock tests for prelims and mains were of great help for self assessment.”

Anu Kumari(AIR 2, CSE 2017)

“I did prelims related test series from InsightsIAS. I revised the questions that I got wong 3-4 times. I did not follow any other test series. I also diligently attempted last prelims revision plan of InsightsIAS”

Nandini K R (AIR 1, CSE- 2016)

“…followed offline prelims test series of Insights and also, prelims cum mains integrated study plan…Initially, I struggled to answer 5-6 answers. But, I was pushed to answer more and more at Insights. In the end I could easily answer all 20 questions in 3hours without diluting quality of answers… Solutions given by Insights were detailed and helped me understand a topic in –depth. I used to score 130+ in Insights offline prelims tests. In CSP-2016, I could score 141+ in paper-1 due to extensive revision of these tests.”

Dhyanachandra H M(AIR 47, CSE 2016)

“…Insights tests are very well designed w.r.t it’s content and approach. Every test exposed the reality in me… The detailed explanations given after tests helped me realize my strengths and weakness…Revision at Insights for Prelims 2016 – Masterstroke. Thanks to Insights tests, I could attend almost 60 questions with confidence within 45 minutes. …”
