There is a list of people who have registered for classes. Each class has a unique ID#.
There are some other columns such as “transaction date”, “receipt number”, “activity name”, etc. But I do not care about those.
Sometimes people will enroll into the same class multiple times. I do not want to include these rows. These are the duplicates I want to delete. That is, any row which has the same “name” and “class id #” value.
How do you do this?
