Because subject 941-210 English writing for business communication teaching two groups. I enrolled group one because second group is full. Cause time is the same to subject 941-311 English oral presentation that teaching on Wednesday at 13.00-16.00 and on Friday at 13.00-16.00. This subject is teaching only a group. So I would like to change group to studying group 2 on Tuesday at 13.00-16.00 and Thursday at 09.00-12.00.
