Can't figure out which modules my students would need to pay for



I’d love to use Code Combat as one small part of my programming course. From my teacher account, I can see:

Introduction to CS
CS 2
Game Development 1
Web Development 1
CS 3
Game Development 2

It’s not clear to me which of these modules are available for free to my students. For example, can they take CS2 and CS3 without paying $10 each month?



Just realized the answer to my question! They would need to pay for the subsequent modules.
