Timetable problem

Yesterday, I went for online course registration. But I made a totally stupid mistake.

I didn't copy down my group number. And today, I found it very hard to know which group I belong to. However, I also have one friend who also having the same problem as mine.

I just need to wait until this evening to check the new group listing. I guess I will just go to class which my friends are going to. Haha..!!
