The question is: why do you allow some duplicate records in first place, when you add them? Maybe your efforts should be put to prevent adding duplicates instead.

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!
