Answer 2

Answer:

No

Step-by-step explanation:

A set is a collection of well defined amd and distinct objects.

Well defined is the key word here.

The term good student is not clearly defined. The person whom you consider as a good student might be considered as not good by your friend.

So, in a nutshell, It is not a set because the term 'good student' is not well defined and the criteria for calling someone a good student might change for person to person.
