Books you actually need So far, (the end of 4th week) you only need books in Math and just textbook in Accounting. You don’t need workbook. The accounting exercises are written in the text book, and there are only templates in workbook. You can do the same template in Excel or Word. The instructor also sends you these templates so really no need in workbook.You definitely need a book in Math. Just a reminder that this book (7th edition) is the same as “Math for Information Technology” published by RRC (this information is correct for 2015 Winter term, so if you read it in the future double check it). Btw, Lena found this book on Amazon.ca just for 6$+7$ shipping. It’s already gone and now the best deal is for 12$ +7$ shipping. They don’t have deals like these in the beginning of the term. The prices were 50-60$ in January. And you don’t need this book: Excellence in Business Communications. I bought the previous edition of the book, but actually I don’t need it at all. There is course content as powerpoint presentations available for all students, and those presentations are everything you need for quizzes and assignments. So, you only need two books plus Lyryx for Math and for Accounting. Lyryx for both will be 68$, and Lyryx labs are 10% of total grades.
