I am about to purchase SM and I have the Textbook, Workbook, HIG, and Teacher's Guide in my cart.
I've been reading the forum and have noticed that some just have the workbook and some have the text and workbook. Does anyone have all the HIG and Teacher's Guide as well? Did you use these? Are they a waste of money, the HIG at $16.50, and the Teacher's Guide at $21.00?
Anyone who just bought the workbook or text and workbook wish that they would have purchase the HIG and TG?
TIA!:D
