Preparation Tips Based on Exam Pattern

  1. Prioritise the Achievers Section: These questions carry 2–3 marks each versus 1 mark for regular questions. Even 5 correct answers here can significantly boost your rank.

  2. Practice Logical Reasoning: This section tests analytical thinking and is not directly curriculum-based, so dedicated practice is needed.

  3. Work on Speed: With 50 questions in 60 minutes, you get slightly over a minute per question. Timed mock tests are essential.

  4. No guessing penalty: Since there is no negative marking, attempt all questions. Never leave a question blank.

  5. Use SOF sample papers: Past exam papers closely reflect the actual question paper pattern.

The SOF Olympiad exam pattern is designed to be fair and comprehensive. Understanding it well gives you a clear advantage in preparation and performance.
