How long does it take to read Source Code: My Beginnings?
At 400 pages, Source Code: My Beginnings is a fairly long book. Expect about 7 hours 20 minutes of reading to finish it, based on 250 words per page and an average reading speed of 230 words per minute. A fast reader will go quicker; a careful read (or reading in a second language) will take longer.
At 30 minutes a day, that is about 15 days of reading. At the median pace of Vread readers, 72 pages per reading day, it takes 6 reading days. For a book of this length (400 to 599 pages), Vread readers who finish it take a median of 5.3 days between the first and the last checkpoint (Vread Reading Barometer 2026).

In Vread, Source Code: My Beginnings is split into 10 checkpoints, one every 40 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 10 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.
