ONGC Recruitment Computer Science

Hello sir I am Lakshay , as I am preparing for the ONGC entrance exam to be held in june so kindly could you please send me the syllabus for computer science for this exam. ??

[Shaleen]

The selection in ONGC will be on the basis of a written exam and interview.

Test Duration:
3 hours

Paper Pattern of ONGC
Test is objective as well as subjective (descriptive):
1) General Awareness (50 Marks):
a. 50 Objective Questions (40 to be attempted, 1 Mark each)
b. 2 Descriptive Type Questions (5 Marks Each)
2) Subject Specialization (100 Marks)
a. 75 Objective Questions (60 to be attempted, 1.5 mark each)
b. 2 Descriptive Type Questions (5 Marks Each)
The specialization section has questions from the discipline in which the candidate has completed the degree for eligibility e.g. Electrical, Mechanical etc.
