What elective classes should I take in my MBA?

When I faced the issue to select electives classes that I would like to take in my MBA, I didn't realize how many different approachs I could use to do it. Now, after I took Decision Modeling class, I can thnk about at least 3 different aproaches: 

1) I have 2 concentrations I want to take for sure (Consulting and Operations). I could have given points to each course, higher points to courses in the Concentrations I want to have and lower points to courses outside those Concentrations. And then, I would maximize the number of points I would have.

2) On the other hand, I those are the 2 Concentrations I want to have, it's because I already have some knowledgement on them (at least I have an idea what they are about). So, to be a more complete and prepered employee, I should take courses outside my concentrations, to give me other perspectives and turn me in a more complete professional. Then I would give higher points to courses outside my concentrations.

3) The third approach I could use is have the constraint to select half of elective courses on my concentrations and half of elective courses outside my concentrations.
