INTERNATIONAL SCIENCE OLYMPIAD (ISO)

SOF is conducting the ISO Olympiad (International Science Olympiad),earlier known as ISO (National Science Olympiad), exam every year by SOF to check out the scientific, logical, and reasoning ability of the students. Student of class 1st to 12th are eligible to give this exam.

Benefits of ISO Olympiad Exam

  1. Each student will received Student performance report that helps the students analyze their strength and weaknesses at different levels, whether it is a state level, national level, or zonal level.
  2. In-depth knowledge of science concepts.

ISO is generally a two-level exam

Level 1

Test is conducted in the respective schools of the participants during school hours.

For Class 1 to Class 10

  • Section 1: Logical Reasoning
  • Section 2: Science
  • Section 3: Achievers Section

For Class 11 and Class 12

  • Section 1: Physics/Chemistry
  • Section 2: Achievers Section
  • Section 3: Mathematics/Biology

Separate question papers for each date of Exam.

English is the Medium of the test.

Test paper are prepared based on CBSE, ICSE/ISC and State Board syllabus.

FAQs

The SOF International Science Olympiad (ISO) is a science competition conducted by the Science Olympiad Foundation (SOF) for students from Classes 1 to 12. It helps students develop a better understanding of science concepts, logical thinking, and problem-solving skills while making learning more interesting and competitive.

Any student studying in Class 1 to Class 12 can participate in the SOF ISO through their school. Schools register interested students for the exam, making it easy for them to take part.

The SOF ISO syllabus is based on the school curriculum followed by CBSE, ICSE/ISC, and State Boards. It mainly covers science topics from the student's current class. The exam also includes Logical Reasoning questions and an Achievers Section that tests higher-order thinking and application of science concepts.

Yes. Students from Classes 3 to 12 who perform well in Level 1 can qualify for Level 2. Classes 1 and 2 have only Level 1 and do not appear for a second-level exam.

SOF ISO rankings are based on the total marks scored by students in the exam. If two or more students score the same marks, SOF uses a tie-breaking process by comparing marks in important sections of the paper. This ensures fair and accurate rankings.

Students should pay extra attention to topics that involve scientific concepts, reasoning, and practical applications. It is also helpful to focus on topics that require calculations, observations, and understanding of real-life science concepts.

Diagrams and experiments are very important for SOF ISO preparation.. Learning how experiments work and practising labelled diagrams can improve understanding and help students answer application-based questions with confidence.
