CBT structure and marking scheme

The information handout published with the call letter sets out the structure of the CBT. Each section is separately timed, and candidates can only attempt questions from the section whose time is currently running.

Section-wise structure

The exam is conducted online, entirely in English, and every question has four options with only one correct answer. There is no negative marking for wrong answers, though the handout advises candidates against answering by random guessing.

Domain Knowledge questions are based on the syllabus for each candidate’s own area of specialisation, as published on the ONGC website. General Awareness covers current and past events.

How ONGC CBT scores are calculated

The handout states that ONGC first works out a Corrected Score for each candidate, based on the number of questions answered correctly in each test. Where a test is held across different sessions, ONGC then works out an Equated Score, adjusting for any difference in difficulty between sessions. Section-wise and total scores are reported to two decimal points.

Documents for candidates who need a scribe

ONGC has published two documents on the call letter page for candidates applying to use a scribe in the exam:

• Format of Medical Certificate — the certificate to be submitted for admissibility of a scribe, in the format ONGC has prescribed: download here
• Joint Undertaking/Declaration Form (Scribe Declaration Form) — a declaration to be submitted by the candidate and the scribe, available on the same official page.

The notice does not state the last date or exact process for submitting these documents. Check the official call letter page for further instructions.

For general documents needed at the centre — such as a photo ID and the printed call letter — the official notice does not give a list; these are usually shown on the personalised call letter after login. (This is added context, not part of the official notice. Confirm with the official website.)
