question about operator bool() const

when checking if an object has valid data do we need to check every private member of the class or only one? For example:

class Student {
     int no;
     float grade[NG];
     int ng;

class Student {
     int no;
     float grade[NG];
     int ng;

In the OOP notes the conversion operator for bool only checks that one member is not zero or true Like this: Student::operator bool() const { return no != 0; } Long story short do we need to check every member is true or only one for it to be considered valid data in an object?
