Common questions

Do I need to install anything to use the apps on a computer?

No. Open /chemistry, /biology, /physics or /parker in any up-to-date browser.

Do the apps work offline?

The study apps keep working without a connection after you've opened them once. Pocket Parker needs a connection to load the map.

Is Pocket Parker part of the study apps?

No. Pocket Parker is a separate everyday app with its own free version.

I'm an instructor. Can I share problems with my class?

Yes, in Chemistry and Physics: in Practice, make a problem set to share as a link or QR code. Every student gets the same problems.
