How is the marks for ntse calculated if there are some questions in which none of the answers is correct?

hello sujal,

i hope you know that there is no negative marking in stage 1 of ntse but it has negative mark of -1/3 for every wrong answer in stage 2.

so In stage 2, if there are some questions in which none of given answers are correct then it'll be dropped while calculating merit list.for further information and details you can refer below link:

This depends on decisions of authority as they evaluate various decisions and according to it such announcement will be made.

So you must wiat for official notifications after results announced.

Meanwhile you can refer to FaQ by NTSE.
