Is there any way of finding out that a newly created question set contains several copies of the same question?

To find this out, please use the application designed for detecting duplicates. The following path will take you to it:

The Information system Teacher [chosen course] ROPOT Question Sets

Locate the question set you want to check for duplicate questions and click on "duplicate". The System will display the list of all the questions that appear in the set more than once and you will be offered an option of removing these.

PozorProvided some questions contain the same text and only differ in form (e.g. use a different font), the System will not consider them duplicates. Likewise, if one of two otherwise identical questions contains a typo, the questions will be considered different and thus will not be listed among the duplicates either. The same applies to the questions of the :r and :c types which contain the same answers listed in different orders.
