Share- I think the difference is between the CAD and CALP plan-both are by the Hellers, but CAD has 4 different options only one of which allows for a complimentary snack. Another difference is that some of the CAD options do not require a salad befor RM as CALP does. There are a few differences, but you should stick with your CALP plan and do follow the book as closely as you can, especially in the beginning-Good luck and nice to meet you!
