I'm finding the whole preference system a bit confusing. Are my preferences for each activity treated individually, or does the system group together all the activities I label '1', for example, and submit that as my first preference timetable? Meaning all the 2s would get grouped together and submitted as my second preference timetable and so on. The reason I'm confused is because if they're treated individually, meaning I could get my first preference for one activity and my third for another, surely it's impossible to avoid a potential clash. This is why I would assume that all my first prefs get grouped together, however for some activities I'm asked to enter 10 preferences, and others only 5, leading to my confusion. Not sure if that made sense but I hope someone can help me.
