Hi,
I am Krishan Kumar, Enrolment no -[protected], took paper of research analyst on 27.03.2022 at 5 15 pm.
they sent link on my mail to start the examination on my registered mail id [protected]@outlook.com with out any set of instruction, do and don'ts.
neither i received my admit card in my registered mail nor in their website, i was looking for admit card but not received from any source. i received admit card in their website after a day of the exam on 28.03.2022.
without knowing "do and don'ts, i unknowingly done some mistake and they terminated my paper in between.
as i was new to NISM and it is my first "exam from anywhere" experience, i literally don't know what to not to do.
its nism sole responsibility to provide set of information to candidates 24 hrs prior to the exam.
i request NISM to retake my exam and let me complete my exam i have attempted 82 questions.
