Science Olympiad for Class 10

Board exam year deserves competitive excellence! It is heard by us and as a result, our CREST Science Olympiad exam Class 10 challenges students positively to compete Internationally, students sharpen skills crucial for board exams and competitive entrances.

CREST Olympiads (World’s Most Innovative & Largest Online Olympiad Exam) conducts an international Science Olympiad for class 10 students. CREST Science Olympiad (CSO) exam is the most competitive internationally conducted Science Olympiad exam. The talents from across the globe compete by participating in the exam to secure a rank. CREST Olympiads by conducting this exam, provide a big platform to students where they can showcase their talent. It helps students to improve their conceptual understanding and grasp tricky concepts.

a. Class 10 is the last class that CSO covers. Students of every board, wherever they live, can enter the Science Olympiad for Class 10.

b. Use your school's registration if it takes part, or register individually on the CREST website.

c. It is a solo exam, online and at home, with the webcam on throughout. Someone else accessing the test, a face out of camera view, or a phone or calculator in use can each get the attempt disqualified.

d. Use a laptop, desktop or tablet whose screen measures over 11.5 inches, with a webcam and a stable internet connection; on Windows, the device must have Windows 8 or later, and a Mac or an iPad is fine too. The latest Google Chrome is the browser to use, with Edge or Firefox as alternatives; the exam does not open in Safari. Phones do not work for it.

e. Level 2 is for Class 10 students who finish in the top 66.67% of Level 1. In any school with more than 25 students in Class 10, the three highest-scoring school-registered students also go through.

1. Revision with a harder edge. The CSO Class 10 topics, from Chemical Reactions and Equations to Magnetic Effects of Electric Current, run alongside your school syllabus, so Olympiad practice doubles as revision with tougher questions.

2. Connections across topics. Heredity and Evolution, Periodic Classification of Elements and Sources of Energy ask you to link ideas, not just recall them.

3. Seeing your own potential. In a Class 10 testimonial, the writer says the Olympiads showed them their potential in a conceptual way, and urges everybody to try them.

4. Beyond your school. A second Class 10 review describes CREST as good ground to improve skills, with Olympiads in many subjects. CSO ranks are given by zone and internationally, so you can see how your Science compares far beyond your own school.

The Science Olympiad syllabus for Class 10 shares no topic name with Class 9. Light returns as Light-Reflection and Refraction, along with Human Eye and Colourful World. Electricity and Magnetic Effects of Electric Current bring electric current back after a year away. Acids, Bases and Salts (last seen in Class 7) and Metals and Non-metals (dropped after Class 8) are back as well. Motion, Gravitation, Sound, Atoms and Molecules, and the cell and tissue topics are not in the Class 10 list.

Section 1

• Chemical Reactions and Equations
• Acids, Bases and Salts
• Metals and Non-metals
• Carbon and its Compounds
• Periodic Classification of Elements
• Life Processes
• Reproduction in Organisms
• Heredity and Evolution
• Light-Reflection and Refraction
• Human Eye and Colourful World
• Electricity
• Magnetic Effects of Electric Current
• Sources of Energy
• Our Environment and its Management

Questions in the Achievers Section are Higher Order Thinking Questions, and they keep to the Section 1 syllabus too.

Pattern: 50 questions, 60 minutes, 60 marks, split into 40 one-mark questions and 10 Achievers questions worth 2 marks. Level 2 is identical and there is no negative marking. The Class 10 Science Olympiad marking scheme page has the full table.

The exam dates for CREST Science Olympiad (CSO) for Class 10 for the Academic year 2026-27 are as given below:

Note: Check Olympiad exam dates for other CREST Olympiads subjects as well.

The exam fee is INR 275 for students studying and enrolling from India. For students studying and residing outside of India, the fee is USD 15.

Your school Science and the Olympiad share most topics this year, so build one plan for both. Eight to ten weeks before Level 1, mark the CSO topics on your school timetable.

Chemistry first: balance equations for Chemical Reactions and Equations, learn the pH scale and common salts for Acids, Bases and Salts, and practise naming and structures in Carbon and its Compounds. Periodic Classification of Elements rewards spotting trends across a period or group. In physics, ray diagrams for Light-Reflection and Refraction and circuit problems for Electricity are where marks are won or lost; do them by hand, as calculators are not allowed. Biology needs clear diagrams for Life Processes and a firm grip on Heredity and Evolution.

One student took CSO International Rank 1 in Class 10. His study method, as his Hall of Fame profile gives it, was to stick to a timetable prepared in advance, one that kept all his other priorities in view. That kind of balance matters when the Olympiad shares the calendar with school tests.

Once the sample papers are done, Olympiad Success, the official preparation partner of CREST Olympiads, offers a Science Olympiad mock test series for Class 10 and one-to-one online classes for topics where you want a teacher's help.

Use the class 10 Science Olympiad sample papers under exam conditions, giving yourself 72 seconds a question across the hour. Take the free trial early, and then the practice tests included in your fee before Level 1.

Plan the last two weeks so they do not clash with your school tests, and keep one full timed sample paper for the weekend before Level 1.
