The service is now open to everyone! We are working full time with both material and software so please continue to send suggestions and feedback on the service.
We are currently working on a feature to add your own notes to the text. We are also evaluating the scoring system and statistics to provide the best possible feedback to your learning.
Slowly but surely we are adding the components that a student needs for the most efficient learning. Our plan is to have more support for Spaced repetition in place within a short while.
