The Vread challenge: 7 checkpoints

  1. Checkpoint 1, page 35
  2. Checkpoint 2, page 70
  3. Checkpoint 3, page 105
  4. Checkpoint 4, page 140
  5. Checkpoint 5, page 175

  7. Checkpoint 7, page 245

In Vread, Thinking in Systems: A Primer is split into 7 checkpoints, one every 35 pages or so. At each checkpoint, a question covers the passage you have just read: a correct answer validates the step, and your progress moves forward like a training plan.

The challenge: validate all 7 checkpoints through to the last page. No giant quiz at the end, no summary to copy out: short questions along the way that prove the book was actually read. It also works as a reading quiz to check your understanding before a test.

Also available in French on Vread.
