PDF eBooks. Students may download or save PDF files to their preferred device (e.g., a desktop, laptop, or tablet).  PDFs can be read offline and hold the entire course in just two files.

Printed materials. Both course files (the Exam Booklet and the Course Reader) could be printed inexpensively by anyone who owns a printer. To further reduce your time and cost, we have put together a printer-friendly version of the Reader.

Website flipbooks. Students may read and "flip" through the pages of the Course Reader on this website, without the need to print or download any files.  A digital flipbook displays content left to right, as opposed to the up and down scrolling of a PDF file.

Physical books. CTS does not produce or sell physical books.  If you click on the image below, we'll provide you with links to services that specialize in converting PDF files into physical books.

Audio. Some students may prefer to listen to the course content through MP3 files embedded on this website.  Please note that these audio files lack the graphics, tables, and practice questions that are available through the reading materials.
