IMPORTANT

Please read the exam pattern carefully.

• The online exam will be conducted through ZOOM.

• Students must attend the exam only using a smartphone. 💡 Computers, laptops are not allowed.

• Please install the ZOOM application on your mobile phone before the exam.

• Make sure your phone is fully charged and connected to a stable internet connection.

• Keep your camera ON at all times during the exam. Use head phone for better quality.

• Students are strictly advised to avoid any form of malpractice. Any suspicious activity will lead to disqualification.

Examiners from the ISSO office will contact each candidate at the allocated time and provide the Zoom Meeting ID and password. Once the candidate joins the Zoom session, the examiner will connect them to the exam portal and share the question paper on the screen. The student must silently read each question and give the answers orally without reading the questions aloud. The examiner will mark the responses based on the answers given by the student. For security and verification purposes, both video and audio of the session will be recorded.

If a candidate does not receive a phone call from the examiner, then the candidate can call on their allocated examiners number or office number.

Time change for attending exam will not be allowed, so every participant is supposed to be present for exam on given time.

Your candidature is purely provisional. At any stage of the Indian Space Science Olympiad (ISSO) Examination, if a candidate included in the rank list does not meet the eligibility criteria, or if any information provided is found to be false, their candidature will be immediately cancelled.

If any candidate is found indulging in malpractice or seeking external help during the exam, they will be asked to stop the exam immediately and will be debarred from ISSO. This rule also applies if malpractice is detected during the post-exam video verification.

Please crosscheck your details and category in the time allocation list below, if found wrong immediately contact customer care department.
