Obtaining books, materials, labs and other resources:
In the details for each course there is a Resources and Materials section that lists the major items you need for each course. The list distinguishes between required and recommended items, and between items you must purchase and items supplied by the teacher. ISBN numbers are provided for all books and media, to help ensure you purchase the correct version of the correct item.
You may purchase items from anywhere you prefer. For unique or obscure items, the Resources and Materials list will provide a recommended merchant. For one-stop-shopping convenience, we recommend you shop first at MBS Direct, a third-party book and media seller that lists all our books and media by course, with guarantees that you will receive the right version for your TPS course. Also, MBS sells to and even ships to overseas locations.
