Rs.800, 700, or even 500 cannot be acceptable.

Paying upfront fee for a university admission is acceptable because it's the applicant who will be benefiting from organization, you pay to get education and it works that way around the world.

Paying for employment is like hanging a victim. It is simply not acceptable.
People, we cannot compromise on our rights. I don't know why some here are suggesting a lower fee, rather we should be demanding TA/DA for those making it to final stage of selection process. Back in 2011 and before, NTS test for employment was free and TA/DA was a fashion.

Organizations contracting NTS have huge budgets, and I don't think well-working Human Resource Departments take a lion's share.
