Teacher's manuals

Teacher’s manuals are available for a number of Cheng & Tsui publications. Because of the sensitive nature of such material, we are only able to offer answer keys to teachers formally affiliated with a school, institution, or homeschooling parents with a Teacher ID card number. We are unfortunately unable to offer teacher’s manuals to independent learners.

When ordering a teacher’s manual from, please provide us with a way of verifying your teacher’s status by writing in the Notes section of your order. This proof can be a link to your name on a school’s website, your school e-mail address, or some other form of verification.
