M5-R5 Practical

The students have to devote 60% of the total time allotted to each module of the course for the practical sessions. Practical assignments have been worked out for each theory module. The Practical examination will be based on M1-R5, M2-R5, M3-R5 and M4-R5 modules of the O Level syllabus.

O Level Project

NIELIT curriculum has a project as an important component of the ‘O’ Level course. The Project is carried out by the student under the guidance and support of faculty and management of the respective Institute / Organization. It is felt that such a project provides an opportunity to the student to apply his / her knowledge and skills to real-life problems (including oral and written communication skills), and as such the project should be given utmost importance and priority both by the students as well as institution faculty/management in respect of its identification, planning, and implementation.

The objective of the Project

The objective of the project is to give the students additional hands-on experience in solving a real-life problem by applying knowledge and skills gained on completion of theory papers in a course at a given level. It provides an opportunity for students to develop written and communication skills.

The project also helps the students to realize the importance of resource and time management, ownership of tasks towards deliverable, innovation, and efficiency in task management apart from presentation skills. It also provides a good opportunity for students to build, enhance and sustain high levels of professional conduct and performance and evolves a problem solver frame of mind in the students. It is also felt that taking up the project by a student prepares him for a job in the industry and elsewhere.

Project Submission for O Level

The student has to submit the project to be ‘O’ Level certified. The project should be original, of real-life value, and not copies from existing material from any other source. The Learners are expected to carry out a project successfully and submit a certificate in the prescribed format from the head of the institute running the accredited course or the organization of which the Learner is an employee. Proforma of the Project Completion A certificate is given as follows.

Download Performa of the Project Completion Certificate

Passing Percentage For O Level

To qualify a module, a candidate must have obtained at least 50% in each theory and practical examination. A successful project completion certificate is mandatory for student to qualify O Level course. The following table shows the marks distribution.

The marks will be translated into grades while communicating results to the candidates. The gradation structure is as below:-


Pass PercentageGrade
Failed (<50)F
>= 50% to < 55%D
>= 55% to < 65%C
>= 65% to < 75%B
>= 75% to < 85%A
