Very confuse about 3u and 2u textbooks? Cambridge btw (1 Viewer)

[Purplelollie]

So Was planning to purchase a cambridge textbook, I do 3u and I was wondering if the 3u textbook includes 2u in there too or are they completely different textbooks and I should purchase both?

You only need to buy the 3U one. They include developmental activities that crossover with a lot of the 2U content.

the 3u includes all 2u topics as well as all 3u topics
