Preparation Tips Based on Exam Pattern
-
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.
-
Practice Logical Reasoning: This section tests analytical thinking and is not directly curriculum-based, so dedicated practice is needed.
-
Work on Speed: With 50 questions in 60 minutes, you get slightly over a minute per question. Timed mock tests are essential.
-
No guessing penalty: Since there is no negative marking, attempt all questions. Never leave a question blank.
-
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.
