After the lottery, if your elective course appears in the course selection list, and the original lottery place is changed to delete (or I forgot not to draw), it means that the lottery has been drawn and the elective course has been successful. If there are no elective courses in the list, you have not won. At this time, you can re-select those that are not full. These can be found on the website of the school's academic affairs office. Come on.
If it is (as if it should be deleted), there is no need to draw lots, then it means that the elective course you selected is not full and there is no need to draw lots.
If you are satisfied, please accept it.
