Why read Drops

Drops are interactive pages made for learning, not just reading.

They're built to help the idea stick.

Move at your own pace
Many pages have a contents menu to jump around and a progress bar so you always know how far you are.
Check what you've learned
Look for knowledge checks and quizzes that tell you straight away how you did.
Turn it into action
Next-step checklists give you a short list of things to do once you've finished reading.
Take it with you
Pages open in your browser on any phone or laptop. Where a creator allows it, you can print one or save it as a PDF.
