Question 15

Answer

Yes. Unless otherwise specified, all zyBooks are beginner-friendly.

Answer

It depends on your learning style and speed. We estimate taking about 48 hours to read through the material and complete the interactive quizzes at regular speed. Each zyBook comes with 1 year access, and you should have more than enough time to complete and revise the material with regular reading.

Answer

zyBooks are like interactive, digital textbooks. By incorporating available technology, zyBooks make learning fun, interactive and engaging – all while drastically reducing the time spent on reading long texts.

Answer

zyBooks comprise the same content as a textbook but with minimal text and maximum interactivity. Interactive charts and quizzes are strategically placed, allowing students to cement newly learnt concepts.

Answer

No. If zyLabs are included, it will be specified in the course page.
