Studying without a network, and getting your answers back

Courses download and can be read without a network; your answers are sent as soon as the signal returns. It is a design constraint held since the very first module, and it works on an ordinary phone and a modest data plan.

What you can take offline

Downloading is triggered from the lesson, on an available connection, and then frees up several hours of work without a network. That is what makes a commute, a break or an evening in a poorly covered area genuinely usable.

  • The full text of the sequence, laid out for a small screen
  • The guided exercises and their briefs
  • The documents shown in live sessions
  • The audio of a session, in a lightweight version
  • Your own notes taken on the lesson

The journey of an answer

  1. 01

    You answer offline

    Answers are stored on the device, with the time at which you wrote them.

  2. 02

    The signal returns

    Sending starts by itself, with no action needed. An unstable network is enough: sending resumes where it stopped.

  3. 03

    The receipt arrives

    Timestamped at the time of writing, not the time of sending. That is what makes offline work usable before a deadline.

  4. 04

    Progress updates

    Stages cleared offline join your tracking, and the tutor takes them into account at your next question.

What phone-first design changes

Content weight

Every lesson is produced for a modest data plan. Text carries the teaching, video supports it.

Resuming after a cut

An interrupted read resumes at the exact point, and an interrupted upload restarts from where it stopped.

Access from across the region

A programme assuming a permanent connection selects its learners. This one starts from the connection actually available.

The volume a programme represents

Offline use is judged on real volumes. The figures below are read from the official catalogue: they give the amount of teaching that passes through this route over a full programme.
