These course objects don't exist in our database. It is due to

• abbreviation was not contained in abbreviation.yaml when courses were updated.
• We cannot resolve cross-listing courses (such as data 100)

To resolve the issue, we should

• Add proper abbreviation and rerun python manage.py course on past years.
• Resolve cross listing courses (it is not too simple I guess. Eli said he would work on this)

Some abbreviations are have changed, so I'm working on updating our abbreviations.yaml appropriately for those courses. Cross-listed courses are a bit harder and will require us to design an appropriate data scheme for representing them.
