Replace A-, A, A+ for A, A+, A++

Suggestion, in your next revision, to use the same scale and colors as EC energy labbeling products for faster understanding.
At least in Europe people are already understand the meaning, since they see it everytime they go buy consumer goods.

So A-, A, A+ would became A, A+, A++
See http://ec.europa.eu/energy/efficiency/labelling/labelling_en.htm

Is just an usability suggestion.

I really don't think adopting an obscure, political (can't have anyone suck, now can we?) energy-related nomenclature would be better than the established international education nomenclature.
