Many consider this program to be the best available! Learn math in 3 easy steps: Watch the Lesson, Do the Problems, Watch a Tutor explain the ones you missed.Complete Set (Consumable Workbook, Non-Consumable Answer Booklet, and 4 CD-ROMs): $149.90 (free s&h in contiguous US). Almost all of our customers choose this option over the CDs-only option below. The main advantage of owning the consumable workbook (in addition to the CDs) is that it prevents students from having to copy down each problem on a separate sheet, which saves them time and helps them to avoid errors. Having a workbook also allows students to continue doing assignments even if their computer malfunctions or they need to work away from home. Another advantage is that the workbook contains written summaries of each lecture, so students can just skim over the summary instead of re-watching the lecture if they forget a key point. Finally, the workbook allows you, the parent, to view the entire course’s content at a glance. Many parents value the ability to see all the problems in a lesson printed on a page, so they can pick select problems for the student to work on. Shipping will come off your order manually.
