The post has covered the NIC Scientist B Syllabus 2025 for Technical and Non-Technical Exams. Follow the official NIC Scientist B Exam Pattern and Syllabus when preparing.
National Informatics Centre (NIC) recruits for several technical posts, including Scientist B posts, for which candidates are required to clear a written test and interview. To cross the cut-off score and get selected for the second stage, candidates must be well prepared with the latest NIC Scientist B syllabus, exam pattern, marking system and other information related to the NIC Scientist B exam. The online test is divided into two main areas, technical and non-technical, as per the NIC Scientist B exam pattern. The post includes the NIC Recruitment 2025 syllabus for both the subjects.
