Packs, also known as mission packs or activity packs, act as a sub-folder under CoderZ Courses and contain missions and other activities, focused on the same topic. Packs will always be part of a course and some courses might even share the same pack.
Teachers can open any pack and any mission in them. Students on the other hand might have some packs locked, depending on how the teacher set the course progress for them.
In Cyber Robotics 101 Course for example, there are 15 packs. On each pack's card you can see the pack name, the number of activities it contains, and a green progress bar to help you see how far you've progressed in each pack.
