What do I need to buy to convert a One Year Condensed program into Year 1 and 2?

If you have purchased B+C or D+E in the past and would now like to use these programs over two years, do the following:

Go to the Year 1 or 2 program you are interested in (e.g. Level D) and click on the What's Included tab.

Click the "Highlight Previously Purchased Items" button.

Add the IG and all the books you do not currently own.
