HOCK international is committed to doing whatever we can to preserve the Earth. This page outlines our GREEN initiatives to protect the environment.
For completely GREEN studying, all of our materials are available to download to your computer in just minutes. If you come across some information that you would like to have in hard copy, you can easily print just a few pages.
Our color textbooks are both attractive and printed using the most environmentally responsible printing technology available. Exclusively from Xerox, Solid Ink technology offers the following GREEN benefits:
All of these environmental benefits come without sacrificing print quality. The quality of our textbooks has never been higher with incredibly sharp, black text and smooth, even coloring on every page.

Our printed materials are shipped worldwide and we are constantly striving to reduce, re-use and recycle packaging.
Unlike many companies that sell software, HOCK international does not use CDs for the distribution. CDs can quickly become out of date, while electronic downloads provide a fast, GREEN way to instantly deliver up-to-date materials worldwide.
CDs are also difficult to recycle because they contain a mixture of plastics, metals and dyes. After being thrown away, these petroleum and metal products can pollute the environment and groundwater.

HOCK is the first and only company providing CMA Materials, CIA Materials and CPA Materials in PDF for use on the iPad and other mobile devices.

The study material is precise and concise. It is written in a well-structured manner. The content is easy to understand because it is supported by good examples and CMA adapted questions. I also want to thank the whole HOCK team for the quick feedback on students' requests.
