yes they are saved in my shopping cart all the way up until you sched. I had classes in my planning worksheet just incase the classes in my s. cart were filled by the time I was able to get my classes. So if I had A100 at 11.15 in my shopping cart and it was filled then I would put A100 at another time( that would fit in my sched ) on the planning worksheet. This way I wasted no time looking for another classes that would work .
