The candidate must be familiar and well-versed with the NIELIT O Level Exam Pattern 2025 to crack the
examination easily. The NIELIT Exam Pattern consists of three stages which are Theory Examination,
Practical Examination, and Project (Certificate only to qualify ‘O’ Level-IT). The exam pattern has
been discussed below in detail:
The Practical Examination will be conducted by the NIELIT in reputed Institutions for all candidates.
The details of the practical examination are given below.
The candidates enrolled in ‘O’ level (IT) course have to submit the Project in order to be ‘O’ Level
certified. The project should be original and of real-life value. The project should not be a copy
of existing material from any other source which will lead to the disqualification of the candidate.
