Class-in-a-Flash thumbdrives come pre-loaded with each title you request. Just plug it into USB port on any Windows based device and click on the book you want. Thumbdrives are a great solution when high speed Internet is not available or simply to avoid the process of downloading.
Thumbdrives may be shared and passed between students, however the drive must be plugged-in in the computer for the books to function. Of course, all eBooks enjoy the advantage of free or minimal shipping costs, revise more frequently than paper books, and are more easily replaced should they become damaged or inoperable.
The purchase of this set includes a free two year revision service subscription for each module. To enter your subscription, simply click into the web page listed on the first page of each book and enter your name and email. For two years, if any change or update occurs in any of these books, you will receive by email a free printable .pdf file of those pages that were revised.
