Good question -- When I first thought about doing this I was just pulling them back in the database, but I found that sometimes they came out of order.

In the controller though, I changed gradeLevels to be  (or what gradeLevels stores from the data-score-levels object) as 
```ruby
@grade_scheme.elements.order(:low_range).pluck(:low_range, :letter, :level).to_json
```
which should force their order to be from low to high.


Let me check into max, but that sounds good to me!
