How computers think, from binary to AI: questions
Who is the How computers think, from binary to AI path for?
Learners aged about 9 to 15. It is a intermediate path, so start at the top and move down the map at your own pace.
How many steps are there?
17 steps in 5 units, about 1.7 hours in all. Most steps take five to fifteen minutes.
Do I have to do the steps in order?
No, but the order is designed so that each unit builds on the one before. If a step feels too easy, skip ahead; if it feels too hard, go back a step.
