Great initiative. It helps very much for preparing w.b.c.s. Interview of successful w.b.c.s officers inspire us to clear the exam. In the new era of technology zero sum helps like a light house.It helps very much who lives in remote place…

The way zero sum has been putting efforts for all the civil service aspirants is commendable. Students have really been benefiting from the help zero sum has been providing. It’s a very reliable platform for preparation for competitive exams in general and WBCS in particular.

Zero-Sum brings a new era in the field of Civil service…this digital platform immensely helped to even an aspirant who is unable to afford a valuable coaching. It gives all the needy things to continue the preparation of civil service. Needless to say this page is improving day by day by their contents. Interactive sessions with the toppers gives guidance and proper strategy to a new aspirant like me.

As I said earlier, like me for many other students who are preparing for WBCS without any coaching, to them zero sum is guider. Though I have not got admission in zero sum still it helps me in any type of queries. Thanks for that. I follow the posts regularly and it helps me a lot to cultivate myself. Now not being a admitted student, I am depending on it a lot….. Expecting that it will help us in any type of problem regarding the WBCS preparation.
