Earn every crown in a Works to get that Works’ certificate. Finish all six Works in Track 0 to also earn the Track 0 badge and certificate, which anyone can verify. Progress and crowns are saved on your own device.

Chemistry practice by course level

ChemTracks organizes the practice tools on stem.oweini.com by course level, from introductory chemistry to general chemistry. Every Works has short lessons, three levels of randomly generated problems with hints and worked solutions, and a crown to win for each topic. ElementWorks, the interactive periodic table, and ChemWorks, the AI study hub, work in every track.

Track 0: Introductory Chemistry

Atoms first. Start here if chemistry is new, or to build a solid base before general chemistry. Track 0 has six Works:

Track 1 and Track 2

Track 1 (General Chemistry 1) and Track 2 (General Chemistry 2) are planned and shown as coming soon. They will continue with deeper electron configurations and periodic trends, bonding theories, redox, enthalpy, equilibrium, acids and bases, kinetics and electrochemistry.

Certificates and the Track 0 badge

Earn every crown in a Works for a free certificate of completion. Finish all six Track 0 Works to earn the Track 0 badge and certificate, issued as an Open Badge with an ID and QR code. Anyone can verify an award.

Frequently asked questions

What is ChemTracks?

Your chemistry adventure, one track at a time. Each track has six practice tools: Track 0 (Introductory Chemistry, atoms first), Track 1 (General Chemistry 1) or Track 2 (General Chemistry 2).

Which track should I start with?

Start with Track 0 if chemistry is new to you. If you are in a general chemistry course, Track 1 is the first semester and Track 2 the second. Track 0 is live now; Track 1 and Track 2 are shown as coming soon.

Is ChemTracks free?

Yes. Every tool is free in your browser, with no account or sign-up. Your progress and crowns are saved on your own device.

Do I earn a certificate or badge?

Every Works gives a free certificate of completion when you earn all of its crowns. Finish all six Track 0 Works to also earn the Track 0 badge and certificate. Each award has an ID and QR code that anyone can check at stem.oweini.com/verify. It recognizes completed practice, not a graded exam or course credit.

What is a crown?

A crown is the reward for mastering one topic. Each topic has three levels of randomly generated problems; a star needs a clean solve with no hint, no wrong check and no skip, and 15 stars earn the crown.
