explanatory text for Add Score System form

This should go at the top of the fieldset for adding a score system:

This form allows you to create a customized "score system" or grading scale.

Each score system needs a short title to identify it to users, for example, if your school's grades go from "A" to "E," the title could be "A-E."

A score system is made up of a sequence of possible scores with decreasing values.

Each score is associated with a numeric point value. For example, in the US, an "A" is usually worth 4 points, a "B," 3 points, etc. This value will be used in any calculations made with the scores, such as finding a grade point average.

Each score is also associated with a minimum percentage necessary to achieve the corresponding grade. For example, 95% and above is an "A," 87% and up is a "B," etc.

Start with the highest score. Click "Add a lower score" to add scores until you have created a score with a minimum percentage of 0.
