Teamwork makes the dream work.

Connect with like-minded students who share your passion for chemistry to strategise, discuss problems, and most importantly - have a blast!

Form teams of 3, 4 or 5 students. All students in Junior College or equivalent are welcome to participate.

Open-book;
the sky is your limit.

At SChL, we don't test your ability to define the enthalpy change of formation from memory. We encourage you to use any tools or reference materials to supplement your existing knowledge, so you can focus on your problem-solving skills to approach our wide range of intriguing questions.

Questions

Do expect a mix of theoretical and puzzle-based problems, covering the physical, inorganic and organic areas of chemistry Some problems may have informative preambles to provide extra context, others may include chemistry-related puzzle clues inspired by games, but all of them are sure to be fun!

Scope

The examinable syllabus will largely follow that of the International Chemistry Olympiad (IChO). However, the final core problems may expose you to content beyond the syllabus, so don't be afraid to explore!
