Feel the rush of adrenaline from the comfort of your homes or at your team's meeting place. All that's needed is a working computer and a stable Internet connection.
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.
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.Refer to Rules ›
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!

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!IChO syllabus ›
Some of us are working, some are studying, and some have been serving the nation since graduating from Junior College. Yet we've all found a common passion for chemistry, from the natural phenomena around us down to the intricate molecular complexity that explains our world. We hope that SChL can be a welcoming and accessible experience for all of you, to take a deep dive into fascinating higher-level chemistry and of course - have fun together!
